[Python-Dev] Python build trouble with the new gcc/binutils

As I sort of expected, this makes the crash go away.  However, it is now
replaced by lots of messages like

building 'grp' extension
gcc -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -fPIC -I. -I/export/spurr1/homes1/ark/Python-2.2.1/./Include -I/usr/local/include -IInclude/ -c /export/spurr1/homes1/ark/Python-2.2.1/Modules/grpmodule.c -o build/temp.solaris-2.7-sun4u-2.2/grpmodule.o

WARNING: removing "grp" since importing it failed

If I put back the dynamic loading stuff and rebuild everything from scratch,
I again get a python that crashes when I try to import struct.
It occurs to me that the traceback from that might be useful.
Needless to say, it is much shorter than the earlier one.

I must say that the "Address 0x2 out of bounds" note makes me suspicious.

Here's the traceback:
