I'll need to run a few more builds to compare apples to apples, but here's some data:

arm-softfloat-gcc-3.3.3-glibc-2.1.3 rc26 fail
arm-softfloat-gcc-3.3.3-glibc-2.2.5 rc26 PASS
arm-softfloat-gcc-3.3.3-glibc-2.3.2 rc26 PASS
arm-softfloat-gcc-3.3.3-glibc-2.3.2 rc31 PASS
arm-softfloat-gcc-3.3.4-glibc-2.1.3 rc31 fail
arm-softfloat-gcc-3.3.4-glibc-2.2.5 rc31 fail
arm-softfloat-gcc-3.3.4-glibc-2.3.2 rc31 PASS
arm-softfloat-gcc-3.4.0-glibc-2.1.3 rc26 fail
arm-softfloat-gcc-3.4.0-glibc-2.2.5 rc26 fail
arm-softfloat-gcc-3.4.0-glibc-2.3.2 rc26 PASS
arm-softfloat-gcc-3.4.1-glibc-2.1.3 rc31 fail
arm-softfloat-gcc-3.4.1-glibc-2.3.2 rc31 fail

Probably I need to copy some patches from gcc-3.3.3 or gcc-3.4.0 to
gcc-3.3.4 or gcc-3.4.1, but there might be something else going on.
I'll see if I can narrow it down a bit
(though if anyone else finds it first, that's fine too...)
