RangeCheckError from RuntimeError

[Jay Michael]

My program was terminating with no runtime error message. When run in gdb, gdb told me it terminated with exit code 52 (I think octal).

I had a Range Check Error. In gdb, I see that _p_RangeCheckError calls _p_RuntimeError. Then, _p_RuntimeError has code that might call _p_RangeCheckError. I didn't trace further -- gdb suddenly becomes unable to single-step, says "Unable to set breakpoint number -37". (The specific number changes if I keep trying to single-step. It's always negative.)

I don't know how much better it would have been, but shouldn't _p_RuntimeError have been compiled with range checking suppressed?

(I've found source for RangeCheckError and RuntimeError. I can't find source for CString2String -- is it an intrinsic function? It seems to have been inline coded in RuntimeError.)

Mine is in gpc-bp.pas

function CString2String (Str: CString): TString;
begin
CString2String := StrPas (Str)
end;

No, Cstring2String is an intrinsic function in gpc.
See e.g. the test file fjf1001.pas: CString2String is understood without
any unit used.

gpc-bp.pas is an help unit to facilitate the gradual conversion of an
old BP program to a new gpc program. See the comment at the beginning of
the unit.
