glibc 2.3 not binary compatible with glibc-2.2.5

[Roland McGrath]

This is a bug in 2.3, pure and simple.  It has nothing to with ABI
compatibility.  When you get a crash that doesn't complain about symbols or
anything like that, there is no reason to presume that it's an
incompatibility rather than just a bug.

A build without -fomit-frame-pointer should work.  Or try putting this
line into linuxthreads/sysdeps/i386/Makefile:

CFLAGS-errno.c += -fno-omit-frame-pointer

then rm linuxthreads/errno* from your build directory and rebuild.

The final fix may or may not be identical to that, but please let us know
if it works.
