--- Comment #1 from Jameson <vtjnash at gmail dot com> ---
I have discovered that the following is also sufficient to generate the same
`cmpl %ebx, %ebx` assembly:
`gcc -m32 -fPIC -O2 -ggdb3  -c alloc.i -S -o - | less`
I tested this using gcc 5.1.1 from Ubuntu 15.04 x86_64.

(search for ".loc 1 583 0" in the resulting assembly to quickly find the failed
instruction sequence).
