Right.

In particular, if the coredump suggests that the internal mutex state is
invalid, this points at memory corruption, and I would suggest
attempting to reproduce with valgrind.

(When I added the print statement, it was so that the compiler would
stop optimizing out this information.  At the time the underlying
corruption issue happened to be in 389ds, though this has of course been
fixed since.)

Thanks,
