Thanks, it took me two hours to produce the core dump, but here it is. I suppose putting it as an attachment is not ok for a mailing list, so I put it on my server instead (tell me if you want it as an attachment instead, I couldn't find that info). See https://lepiller.eu/files/core (400KB) and https://lepiller.eu/files/test-lib (2.7MB) (the program that dumped core). Thanks for your help!
Thank you,
as I don't have arm at hand, can you provide
gdb .test-lib core
bt full
output?
