Here is the testcase:
dirtyepic ~ $ cat pr27364.S
.tfloat 1.442695040888963407359924681002
dirtyepic ~ $ gcc pr27364.S
pr27364.S: Assembler messages:
pr27364.S:1: Fatal error: failed sanity check
This is from sysdeps/x86_64/fpu/s_expm1l.S:40 in glibc. It produces the error
when we attempt to compile glibc with a binutils-2.16.91.0.* or 2.16.92 built
with GCC trunk.
