hmm, maybe you are right regarding OffsetOut. I can spot the
difference here (see how it crashes also with n_free):
(
s.waitForBoot({ fork {
SynthDef(\test, {
var z;
z = SinOsc.ar;
Offset.ar( 0, z ); // no crash with Out instead
}).send( s );
s.sync;
s.sendBundle( nil,
[ "/g_new", 1007, 0, 0 ],
[ "/s_new", "test", 1011, 1, 1007 ],
[ "/n_run", 1011, 0 ]);
s.sendMsg( "/n_free", 1007 );
}});
)
... and also i realized i was still using OffsetOut in Eisenkraut
(since a while ago i thought that it had any precision advantage
over Out, but i never really understood what OffsetOut was doing and
why it would be more sample accurate than Out when not using bundle
times). So i replaced all OffsetOut with Out in Eisenkraut, and some
mysterious scsynth crash bugs disappeared straight away...

I noticed Sciss's n_free bug in the bug tracker, and noticed in the
console output that OffsetOut's Dtor was involved. I tried a couple
of test cases with Dtor UGens, and they all crashed, but the
following example didn't:
s.boot;
SynthDef(\test, {
Out.ar(0, SinOsc.ar(440, 0, 0.1))
}).load(s)
// now either of these:
(
s.sendBundle( nil,
[ "/g_new", 1007, 0, 0 ],
[ "/s_new", "test", 1011, 1, 1007 ],
[ "/n_run", 1011, 0 ] // REQUIRED TO PRODUCE THE CRASH
);
s.sendMsg( "/g_deepFree", 1007 ); // Doesn't BOOOM!
)
Perhaps the bug has to do with the deepFree doing something wrong
with Dtors? I don't really know where to look for this... I'll poke
around some, but in case this rings a bell for anyone, I thought I
would post it!
Best,
Josh
