Hi

Not really, it was compiled on Alpine with musl libc and with stripped
debug symbols, so i cannot get reasonable backtrace from that, and then
forgot about that during holidays.

Considering it is triggered in by 'show ospf topology/state', it may
be issue there, probably related to big stack allocations there (which
should be changed to some linpool allocations).

Now i did a quick search that musl changed default stack size to 128 kB,
so that is possibly to be hit in that code.
