frequent segfaults with 1.0.0, maybe caused by plugin ? about qtractor

[rncbc]

latest gmsynth.lv2 includes its own copy of (lib)fluidsynth, statically linked.

dunno why the arch version still dynamically links to system libfluidsynth.so, which links to libinstpatch.so in turn and ultimately to glib.so which is probably the root cause of your problems.

thanks for looking at this. Not sure I'll be able to dig further; I wasn't able to reproduce the problem with other software (carla, ardour).

the gmsynth.lv2 package from archlinux.org is really something: it explicitly patches the x42's upstream source code to exclude the bundled fluidsynth static code in favor to system shared libraries... (can't argue with that it's a arch's packager call for x-sake)

just build the plugin from source (https://github.com/x42/gmsynth.lv2) and you can confirm for yourself...

besides, v1.0.0 is not the current recommendation anymore, go with v1.1.1 at least.
