> This is correct, vla and alloca always uses a frame pointer because there is no way to get back to the original offsets so the compiler needs a frame pointer.

It's not restoring from the frame pointer here, it's restoring from ecx. 'addl
$8, %esp' would work just as well in the function epilogue, like it would if
this function had no VLA.

Disabling inlining does fix that problem, though.
