Is this a regression, or memory corruption from something else?
It looks like somebody tried to free() twice the same pointer
(if you look in the log you will see a BUG message about it, including
the file and line where it was free()'d first).
This is with CANCEL_REASON_SUPPORT #undef'd in tm_reply.h, btw.
