Confirmed on i?86 as well, even with 4.3 headers:

I consider emulation of decimal FP to be part of the compiler's job. Part of
that emulation is setting the FP execption flags as per IEEE-754-2008.
There is one set of FP exception flags (used for both binary FP and

For

we somehow compute the wrong ESCAPED solution.
ESCAPED = { NULL ANYTHING ESCAPED NONLOCAL a b D.15681 }
this is missing a.32+32.
Bah, it turns out I again

Hm, we are remapping
iftmp.1_6 = (struct A[0:n.0 + -1] *) D.1755_5
where the variable array pointer type contains in TYPE_SIZE_UNIT n.0_3 * 4
and n.0_3 is on the free list.
I wonder how we end up with an SSA

Result unreproducible under the same compiler version and same compile options
on a OSX 10.5.6 core2duo host. Both 'flat_assignment_ai' and
