Comment (by danielk):
There are no invalid writes in that valgrind log, which is what I was
hoping for.
There are plenty of double frees, mostly due to using QString's accross
threads without making a deep copy. But these usually don't cause a
SEGFAULT.
Can you set the environment variable MALLOC_CHECK_ to '1' and see if you
can reproduce the crash? If no, please send me the backend's "-v record"
log with the malloc messages embedded (which may be redirected to stderr
rather than stdout.) If you can still cause the crash, can you try setting
MALLOC_CHECK_ to '2' and get a backtrace from that.
