FWIW the test case works fine on cvs trunk.
It does fail for me with 4.0.

Using -O2 or greater, when taking the address of an input argument results in
the wrong code. For example:
int foo (double d)
{
int *p = (int *) d;
return (*p);
}
With -O2 results in:
foo:
movq-8(%rsp), %eax
ret
With -O1 results in:
foo:
movsd %xmm0,

Test-case.
If compiled for x86_64 with -O2 or greater, results in bogus code.

I am not sure the underlying problem is fixed. The assembly language error
seems to come from the line:
.pred.rel.mutex p0, p1
p0 is a fixed predicate register and should never show up here. p1 is not used

You haven't said how you configured GCC. I'm guessing you configured for
arm-linux, but with an AAPCS-compatible ABI; you can't do that. The error isn't
the greatest, but it's hard to guard against all

Abort just comes from
The configure switch --enable-version-specific-runtime-libs
