FYI, this issue was resolved and didn't have anything to do w/ realtime prio

SVN commit 1134129 by pedrol:
ALSA backend. Removed a call to ALSAMIDIOutput::reloadDeviceList() from the
MIDI event handling thread, because this method is not thread safe and it is
not needed since 2.3.0 anyway. This fixes an ugly crash.
BUG: 240394
M +1 -1 CMakeLists.txt
M +2 -4 alsa/alsamidiobject.cpp
M +0 -3 alsa/alsamidioutput.cpp

https://bugs.kde.org/show_bug.cgi?id=240391 remains open and
unconfirmed; similar to the other bug, I hypothesize that it's
multiple threads freeing the same piece of memory, or some other
thread-related malloc-clobbering. I can routinely crash on a 4 core
machine, and more infrequently on a 2 core machine. Haven't tried
locking to one core to see if that resolves the problem, or whether
the threading/corruption issue from the other bug is also the cause of
this problem.
