digitalmars.D.bugs - windows "-g" flag necessary to correct code generation

Compiling the DUI OpenGL test programs without
the "-g" flag generates code the will produce "Access Violation".
with the "-G" flag the code run correctly.

How can I demonstrate this
without the full DUI library?

DUI opengl make use of mixins (I don't know if that's relevant).

The first thing to do is find out where the problem is happening. Compile
the code without -g, but link with -g. Then run it under windbg.exe, which
will pinpoint the location.

It seems this might be related with extern(C) instead of extern(Windows).
I'm checking that.

BTW
seems 
version(Win32) extern(Windows):
else extern(C):
glFunctions...
glFunctions...
glFunctions...

doesn't work... do I have to duplicate the functions under
each version?

It works when I try it: ----------------------------------- version (foo) { extern (Windows): } else { extern (C): } int foo(int x) { return x; } ---------------------------------- compiling with: dmd -c test and: dmd -c test -version=foo produces different callign convention versions of foo().

I'll try it again tonight... Ant
