Yes, that's good.

Unfortunatly this backtrace at least to my untrained eyes doesn't
offer an immediate solution, I dare not even to guess. Some things you
could try would be: It crashes in "fluid::fluid_init", which gets
called when the [fluid~] object gets created. You could uncomment this
temporarily by putting "//" in front of line 56 as in: 

55:            AddOutSignal(2);         // 2 audio out [ == AddOutSignal(2) ]
56:            // fluid::fluid_init(argc, argv);
57: 

and recompile with flext's build.sh. 

If you then can create a [fluid~] object, you may be able to crash it again by
sending a message [init( to [fluid~] which calls the initialization in
"fluid::fluid_init" manually. Anyway both of these should give different
backtraces. 

Another thing you could try would be to use the Pd as it is in CVS currently,
unless you already do so. That's what I'm running here and with that and flext
and fluid~ from CVS I cannot reproduce the crash.
