GCC 4.4.0 compiled glibc 2.10 works just fine for me on x86_64, i586, i686,
powerpc and powerpc64.
Anyway, if you say GCC 4.3.3 compiled glibc 2.8 works and 4.4.0 compiled
doesn't, then please do a binary search between 4.3.3 and 4.4.0 compiled
objects to find out on which CU it matters (say configure glibc with CC=gcc
CXX=g++,
then point PATH env var. to wher eyou have gcc 4.4.0 unpacked, build glibc,
verify your testcase breaks, then in the build tree
for i in [a-l]*/*.os; do mv ${i}{,.4.4}; done
change PATH to point to 4.3.3 gcc, make, see whether your testcase breaks or
not and depending on that continue with either half of the [a-l]* or [m-z]*
objects, etc.
