seg fault building glibc on x86_64

[Chris Eveleigh]

we appear to be getting a crash when attempting to rpmbuild glibc-2.9-3
on an up to date F10 x86_64 system.

i can build it fine on an up to date F10 i386 system.

this has come up in https://bugzilla.redhat.com/show_bug.cgi?id=473445

can anyone reproduce/fix/suggest?

it seems to crash at different places - for example:

rpmbuild/BUILDROOT/glibc-2.9-3.x86_64/usr/share/zoneinfo/right/Asia/Riyadh89] Segmentation fault (at least twice)
rpmbuild/BUILDROOT/glibc-2.9-3.x86_64/usr/share/zoneinfo/right/Australia/Darwin] Segmentation fault
rpmbuild/BUILD/glibc-20081113T2206/build-x86_64-linuxnptl/sunrpc/xmount.stmp] Segmentation fault
rpmbuild/BUILD/glibc-20081113T2206/build-x86_64-linuxnptl/sunrpc/rpcsvc/sm_inter.stmp] Segmentation fault

i can't really see /what/ is crashing, you just get a line like:
make[2]: ***
[/home/cje/rpmbuild/BUILDROOT/glibc-2.9-3.x86_64/usr/share/zoneinfo/right/Australia/Darwin] Segmentation fault
