Hi,

I can easly reproduce this issue with gdb 8.2, after loading (quite huge) one
of ScyllaDB binary. Backtrace is following:

top-gdb) thread apply all bt

As I see crash comes from unwinder (frame.c) so I used "set debug frame 1" to
produce more debug output during unwinding process.
Full gdb dump is attached.
Hope it helps.
