Can you take a look at the assembly output to see if
the stack is realigne

H.J, this was introduced by your commit:

I've configured a minimal 4.3.5 compiler, and testing shows that
extern void f (_Decimal128);
void g(void)
{
__builtin_alloca (2);
f (0);
}
which also fails with the same ICE with 4.5.0 and 4.4.4, actually works wit

_Decimal128 has the same problem, and is supported by gcc 4.3, so this may
trigger there too (but I don't have 4.3 installed to check right now)

Confirmed. GCC 4.3 rejects the code (no __float128), so not a regression.
