AFAICS, the compiler figures out that the called function requires only 64bit
alignment and lowers the alignment requirements at the call site. So, although
the callee is not leaf, it gets "misaligned" to 64 bit.

If there are additional requirements for the alignment at call site (c.f.
Description), then the patch in Comment #2 is correct.
