[AlexTP]

CudaText (souce in Github) now crashes if run in debugger and w/o debugger (not always).
lazutils/laztracer.pas

Code: Pascal  [Select][+][-]

1.     procedure RaiseGDBException(const Msg: string);
2.     begin
3.       DebugLn(lrsERRORInCode, Msg);
4.       // creates an exception, that gdb catches:
5.       DebugLn(lrsCreatingGdbCatchableError);
6.       DumpStack;
7.       {$ifndef HASAMIGA} // On Amiga Division by 0 is not catchable, just crash
8.       if (length(Msg) div (length(Msg) div 10000))=0 then ; /////here
9.       {$endif}
10.     end;
