Segmentation fault #69
Description
I didn't use meka for quite some time. This was likely the first time I tried it under Fedora 33/x86_64.
Most of the times I start meka-20210726 I get a segmentation fault.
Backtrace:
Thread 1 "meka" received signal SIGSEGV, Segmentation fault.

I also downgraded to meka-20191213 and I have the same behaviour.
