--- Comment #18 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
It seems the problem is not in CCPortLatency::Create, but rather one of its
callers. Try to investigate in gdb where a misaligned pointer is derived from a
64-byte aligned pointer to the toplevel g_trex object (i.e. work up the stack
from the point of the crash).
