Hi,
SET has a patched version of gcc 2.7.2.1 on his homepage that 
supports the stabs debugging info format. Compiling
C++ code with -gstabs allows some nice debugging possibilities
that the usual -g does not. However, running strip.exe on the
executable seems to ruin the image, I guess already the startup
code. The only thing you get is a "General Protection Fault",
nothing else. 
The message is:
General Protection Fault at eip=123a flags=3246
and some registers...
No stack traceback, so I guess strip screws up the image
quite completely.

(Trivial) C code seems not to be affected, although I didn't try
a more complicated source. 

Eli proposed to use -gxcoff instead, but that only gets you a warning
"debugging format not supported by this version of gcc".

I am not sure if 2.8 supports stabs, but I guess that if so, strip.exe
will ruin those images, too. The only way around this, so far, is
to rebuild all without debugging info...

Ciao
Tom
