Hi. I have MeshMixer appimage created from and older version of Meshmixer.yml. It worked well on Fedora 26, but after upgrading to Fedora 27, it segfaults upon launching. I wonder, what would be the best way to debug the problem? gdb complains for missing debuginfo RPM packages, but given it’s appimage, I don’t think my Fedora debuginfos would help it.

Do you need "set solib-search-path" or "set sysroot"?

Missing separate debuginfos, use: dnf debuginfo-install pcre2-10.30-2.fc27.x86_64
Note that I the last mentioned command says I already have pcre2-debuginfo-10.30-3.fc27.x86_64 installed.
I will try to recreate the appimage and see if it still segfaults, but in the meantime, is there a way to debug this somehow?
Thanks.
