when i try to compile gnustep using gcc-2.96 as shipped with redhat 7.0 gcc
exits after a segmentation fault. this is reproducable using the current
gnustep version from cvs or with the last released version:
ftp://ftp.gnu.org/gnu/gstep/gstep-core-0.6.6.tar.gz

the following is the output of gcc (after doing a simple configure
successfully first, of course):
gcc NSData.m -c  -DGNUSTEP_INSTALL_PREFIX=/usr/GNUstep/System

as the gcc-maintainers will not support the snapshot redhat used for rh 7.0
i hope you can resolve the problem (or perhaps give a hint about the
"offending" source in NSData.m).
