My setup was broken, I can reproduce the issue with the session variables.
I managed to get a useful Valgrind trace:

have their globals initialised. If we only initialise the filename
fields in MINIT, then the threads have an uninitialized value. If the
uninitialized value is not NULL, this leads to segfaults upon access.
