If you have enough guts to keep Castalia enabled and have Delphi Berlin or higher, then you can use this shortcut:

I could not find any official place where ReturnAddress is documented even though it is used at quite a few places in the RTL, VCL, FMX and 3rd party libraries like DUnitX, Spring4D, JCL, ReportBuilder, TeeChart.
I tried searching it in the contexts of Delphi 2007, Delphi 2009, but there is only a [Archive.is] different System.ObjAuto.TParameters.ReturnAddress documented in XE2 and higher.
procedure Abort; begin raise EAbort.CreateRes(@SOperationAborted) at ReturnAddress; end;
There is a (usually broken*) ReturnAddr function used in various places of the RTL/VCL/FMX and (therefore wrongfully copied) in many other peoples code.
function ReturnAddr: Pointer; // From classes.pas asm MOV EAX,[EBP+4] // sysutils.pas says [EBP-4], but this works ! end;
Related to the above is the documented ExceptAddr.
I’ve used this in my ExceptionHelperUnit to build a GetStackTrace function in the example gist below.
I found these posts documenting the behaviour of the above intrinsic functions and more:

[WayBack] I love installers that can download and install in parallel threads. Embarcadero and Zypper can learn from this. – Jeroen Wiert Pluimers – Google+
Most Linux distributions have package managers that can do this (apt and yum can), but OpenSuSE zypper (actually ZYpp) cannot even download packages in parallel:
Embarcadero is in the same state as zypper.

A few notes for managing the users that should be allowed to send mail via sendmail using TLS authentication.
Most of it is derived/summarised for [WayBack] SMTP AUTH in sendmail 8.10-8.13 and [WayBack] Creating Users for a Postfix-Based Mail Relay – Scott’s Weblog – The weblog of an IT pro specializing in cloud computing, virtualization, and networking, all with an open source view
# sendmail -d0.1 -bv | grep SASL
NETUNIX NEWDB NIS NISPLUS PIPELINING SASLv2 SCANF SOCKETMAP/etc/passwdSASLv2 or older. For SASLv2 they are:
/etc/sasldb2 has the users/passwordssasldblistusers2 lists the userssaslpasswd2 manages usersFor instance, this commands creates a new user for use with sendmail:
# saslpasswd2 -c -u example.org firstname.lastname
Password:
Again (for verification):
firstname.lastname@example.org: userPassword
....................firstname.lastname@example.orguserPassword
For future reading:
not found in sasldbI thought I needed this so I could add an alias @pluimers.com to my gmail box, as I read only the accepted answer at [WayBack] Add new alias to Gmail without SMTP (forwarding-only address) – Web Applications Stack Exchange pointing to:
[WayBack] External Addresses No Longer Use Gmail SMTP ServersI should have read the second answer at [WayBack] Add new alias to Gmail without SMTP (forwarding-only address) – Web Applications Stack Exchange:
As of writing, however, you can simply use the Gmail SMTP server, as long as you use [WayBack] Google two-step authentication.
So just for completeness, the full steps:
- Gmail settings, Accounts and Import tab.
- Add another email address you own
- Type name and email address to be added.
- For SMTP Server, put
smtp.gmail.com- For Username, your full Gmail address including
@gmail.com- For password, provide an App Password generated in Google Accounts at https://security.google.com/settings/security/apppasswords
- Leave Secured connection using TLS selected as is.
- Add Account

If you get this error:
Backup and Restore failed and you receive the following error message: The backup did not complete successfully. Check your backup: Windows Backup skipped backing up system image because one or more critical volumes is not having enough free space.
then you are dealing with error 0x81000033 which usually means your SYSTEM RESERVED partition is full, but might happen on other volumes you are backing up as well.
Windows tries to trick your mind, as the error actually indicates the disk you make your backup to, but in fact it is about one or more of the disks you are backing up.
Most often, this is the hidden partition SYSTEM RESERVED (sometimes called System Reserved):
The
SYSTEM RESERVEDpartition (~100 megabyte on systems originally installed with Windows < 8 and ~350 megabyte afterwards) contains files relating to boot, recovery and BitLocker drive encryption. You find more information about it here:
The minimum free size for volumes when using Windows backup are these:
That was indeed the case on my disk:
System Reserved volumeA quick search for 0x81000033 reveals space issues usually are about the USN Journal which you can configuring using fsutil.
Even though the documentation doesn’t tell, fsutil accepts not just a drive letter as VolumePath, but also a VolumeName. [WayBack] 1_multipart_xF8FF_3_WolfC07.pdf (Chapter 7 of “Troubleshooting Microsoft Technologies: The Ultimate Administrator’s Repair Manual“) gets that right:
volumepath … specify the path to a logical volume (drive letter, mount path, volume name).
So you do not need a drive letter to disable the USN journal, the volumename suffices.
This volume name is the unique NTFS identification for a volume: [WayBack] NTFS Curiosities (part 2): Volumes, volume names and mount points – Antimail
You can find the volume name inside PowerShell by using Get-Volume | Format-List, then on an administrative command prompt running this:
fsutil usn deletejournal /D \\?\Volume{b41b0670-0000-0000-00e8-0e8004000000}\
In my case this wasn’t enough, so I had to assign a drive letter to see that there was a snapshots directory in the root:
Deleting that directory solved the problem.
