Hm, maybe misbehaving plugins?
Try running MusE with the -2 command line option to disable loading LV2 plugins and see what happens.

Hm, looks like you have multiple VST paths loading the same things?
Try with the -N command line switch as well to disable VST and see how far we get.

If you get in, examine your Settings dialog, Plugin Paths, and make sure there aren't multiple
paths pointing to the same plugins (or plugins with the same names).

Cool.
When it says "already exists", that is a sign of duplicate paths, but that is fine, it ignores the duplicates.
So that alone is not causing the crash. It must be a specific plugin.
Also, you seem to have a .dll file somewhere in those paths that is not a VST plugin. That's the "entrypoints not found" thing.
Want to know which file? Use the -D switch and look for the phrase
" VST 2.4 entrypoint VSTPluginMain not found in library xxx.dll "
which will appear just before the similar first line of your first post.

Want to know which VST plugin is crashing? Post the results of the -D switch for better debug info.
It will likely show it is loading a particular plugin just before it crashes.

I uh... guess were gonna have to expedite that plugin scanner that FalkTX has been asking for, eh? He he...
New plugins out there always appearing.
Spamatica has put a todo on the bug reporting site. Wonder if he's working on something.
I'm thinking of some ideas of how to implement.

Re: MusE crashes all of a sudden

Postby Tim E. Real » Tue Apr 10, 2018 3:50 am

Did you manage to isolate the problem?
Hm, here it looks like it's crashing after the very last plugin has loaded, assuming ZamVerb_dsp is the last one found.
I mean it appears unlikely that ZamVerb_dsp by coincidence would be the culprit, unless there really are more plugins to be found after it!

Can you show the VST ones like before, by using the -2 switch?

Might be MusE's fault. Sometimes (plugin support) corruption bugs don't crash until after they're loaded, after the system gets going,

Also what muse version? Tried latest git master?

I did try to add a plugin cache but it got complicated and I didn't really have time to dig in, so currently I'm not doing anything :(

ok so I've uninstalled linvst, removed all vst paths in the plugin settings except for the dssi as I don't know if that's needed by MusE and ran MusE with:

Not entirely sure what you mean by Removed all vst paths, looking at the screenshot it certainly seems to load a lot of VST plugins.
Can't remember of the top of my head but it could be that MusE also tries what's listed in environment variables VST_PATH and VST_NATIVE_PATH.

Please try the other startup parameters for disabling plugins (p=LADSPA, N=VST, I=DSSI, 2=LV2),
muse3 -pNI2 starts muse without any plugins. A good starting point for knowing if it's a plugin problem.

I'm a bit confused about the 'Killed' part in the printout, does MusE print that? I don't seem to remember seeing such a printout when MusE crashes. Could be a plugin printing it I guess.

Another way to isolate the issue is to start muse through gdb.
Something like this:
gdb /usr/local/bin/muse3
And when gdb has loaded type 'run'
When the crash comes, gdb will halt the application and show the point where it crashes, typing 'bt full' on the prompt will list the entire call stack. This should hopefully give enough information.
