Dear Maintainer,
I tried to reproduce this segfault.
Unfortunately this did not work as expected.
The segfault in multi-thread did not show up.
But I received one in multi-dict (in e.g. 3 of 6 runs).
This was done in a up-to-date unstable amd64 VM,
running at a AMD cpu, 16 threads given to the VM.
The segfault did manifest in each case in libhunspell.
This seems to be caused by the static variable "utf_tbl"
possibly being shared between threads, and being freed and
initialized while maybe used in another thread.
Kind regards,
Bernhard
