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.

February 1st, the start commences of Sunsetting Mercurial support in Bitbucket – Bitbucket [WayBack]. Starting June 1st, only git is supported by Bitbucket, despite them having started with and focused mainly Mercurial at first.
Here are the major dates of the sunset:
- February 1, 2020: users will no longer be able to create new Mercurial repositories
- June 1, 2020: users will not be able to use Mercurial features in Bitbucket or via its API and all Mercurial repositories will be removed.
All current Mercurial functionality in Bitbucket will be available through May 31, 2020.
So by now you should have started migrating from Mercurial to git, probably away from BitBucket.
