--- Comment #4 from Peter Hutterer <peter.hutterer at who-t.net> ---
fwiw, I tried reproducing this with 0.5.0 and 0.6.1 (on fedora) and could not
get the crash to happen. that's with a count of up to 200 and also with the
sleep removed, neither reproduced it here.

given the backtrace shows xkb_keymap_new_from_buffer() and the actual failure
is in xkb_context_ref() I would assume this is an SDL bug rather than a
libxbkcommon bug. The only thing that can segfault here is the ctx argument
which is provided by SDL. This indicates that SDL may not initialize the
keymap, or that some memory corruption happens, or that the keymap failed to
initialize but everything continued as normal

valgrind may tell you more
