Alexander Monakov <amonakov at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |amonakov at gcc dot gnu.org --- 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).
