I can't compile glibc from glibc-2_3-branch. It fails on:

The same source builded in the same enviroment but optimized for i686, i586,
athlon and sparc compiles correctly.

Build logs are not very useful.  Please try to extract a self-contained
test case and attach it to this problem report.

Probably this is not easily fixable in GCC.  A reload failure in an asm
means you're just out of registers, and usually the problem is not with
gcc but with the asm constraining the compiler too much.  But maybe the
problem can be resolved, who knows.

Without a test case, we cannot help you ;-)

It would also be helpful if you could tell us if earlier GCC versions
did not cause this problem for you.
