There is a reression that causes programs to crash if they use SysErrorMessage and HeapTrace.
program test; uses sysutils; begin writeln('SysErrorMessage(193)=',SysErrorMessage(193)); end.
It'll crash with an errormessage like "Marked memory at $001C4D78 invalid". Fixed in revision 35246. Bart 2017-01-07 22:58
The regression is caused by r33823 (merging of r33363 to fixes branch).
