For now, I’ve turned off the feature that seemed most suspicious...
https://github.com/tautologyclub/feebleline/issues/66
If it turns out that I don’t have any crashes then great! Otherwise,

Sure, though I forgot to save the core file last time, so I can’t press
"l" in gdb, but here are indicative code snippets from the files named
in the previous backtrace. The mentioned lines are marked below:
... M-x occur RET /\*[0-9]+\*/ RET
Thank you!
