Now I tried installing the packaged libqt5pas and still see no segfault.
Note that this isn't a fresh install, I dist-upgraded it (or better
do-release-upgraded it) many times, but I don't think that should
matter.
IMO, fpc version is important. fpc-3.0.4 from distro crashes,
Does anybody have a stack dump of the crash? Maybe it's related to the
stack alignment issues which are fixed in 3.2+?
This is crash dump - Fedora 30 64bit , fpc-3.0.4, Qt5 lcl.
