All recent 0.9 variants and the 1.0 preview.
I noticed that much of its compiles are being done with -O3. I believe other
programs had problems with this as well, that recent gcc/g++ et al are
untested with optimization levels other than 1. Lmms-0.3 is compiling with
-O2. See if that works.
Anybody had the problem? Fixed it?

Ok, interesting.

Not really.
What distribution are you using?
How was it compiled?
Does it segfault directly on startup?
Do try to enable core dump generation (usually with ulimit -c unlimited)
and check the core file with gdb <binary> <core file> and see what it
has crashed on. Since your binary is probably built without symbols it
might be a bit terse, still it might give some clues.
Or try rebuilding with debug enabled.
Regards,
Robert

Using Debian Sid, fairly up-to-date but full upgrading is a mess right now.
Gcc,g++ are most recent.
Muse is compiled with VST enabled. Tried with and without processor specific
compile and optimizations. That -O3 seems hard wired in the sub-folder
Makefiles.
Muse 1. Checks for Jack
2. Checks ladspa plugins (complains about some of them lacking a symbol but
will still segfault if I run with "-p").
3. Attempts to reserve a slug of memory.
4. Segfaults. (The above may or may not be the problem)

I could try a dbg run and post the traces.
