GCC 20130526 (r199345) - works:
08048a10 <main>:
main():
[...]
8048a62: mov $0x8048f60,%ecx
8048a67: mov $0x8048f80,%edx
8048a6c: mov $0xa1,%eax
8048a71: call 8049790 <htab_create_typed_alloc.constprop.9>

08049790 <htab_create_typed_alloc.constprop.9>:
htab_create_typed_alloc.constprop.9():
8049790: push %ebp
8049791: mov %edx,%ebp
[...]
80497e8: mov %ebp,(%edi)
[...]
GCC 20130609 (r199874) - fails:
08048a10 <main>:
main():
[...]
8048a62: movl $0x8048f80,0x8(%esp)
8048a6a: movl $0x8048fa0,0x4(%esp)
