Testers 3.0.2

There is a reression that causes programs to crash when they uses 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".
The regression is caused by r33823 (merging of r33363 to fixes branch).
