Since you're using Mac OS X, you may be able to find some log information by using the Console application, which should be found in the Utilities folder in the Applications folder. Console should have something to say about any program that abruptly exits; although that's not much consolation, I'm sure that's why they call it Console.... In any case, the preferences for Console should have a setting to ask it to alert you when there's a new log entry, which means it can pop up after every crash.

It may also be helpful to know what primitive crashed the VM. I can't reproduce this on my machine, but it looks as if that button sends #record to the RecordingControlMorph. Can you use the debugger to step through the code to find the crashing method? Open an inspector on the RecordingControlMorph, type "self record; record" into the lower pane, and choose "Debug it" from the yellow-button menu.

Good luck with it!

Hmm, I'm still on 3.8.17b5 and it works fine there.

• Bert -

Which Mac OS X version ?

Karl

Ah, that would be this routine below (see the assert)

// deallocate a Stream. // void Stream_delete(Stream *s); void Stream_delete(Stream *s) { assert(s && s->buffer); Buffer_delete(s->buffer); dprintf("stream %p[%d] deleted\n", s, s->direction); free(s); }

That is called either via

// shut down sound output. // int sound_Stop(void); int sound_Stop(void) { dprintf("snd_Stop\n");

if (output) { Stream_stop(output); Stream_delete(output); output= 0; } return 1; }

or

int sound_Start(int frameCount, int samplesPerSec, int stereo, int semaIndex); int sound_Start(int frameCount, int samplesPerSec, int stereo, int semaIndex) { Stream *s= 0;

dprintf("snd_Start frames: %d samplesPerSec: %d stereo: %d semaIndex: %d\n", frameCount, samplesPerSec, stereo, semaIndex);

if (output) // there might be a change of sample rate sound_Stop();

if ((s= Stream_new(0))) // 0utput { if (( Stream_setFormat(s, frameCount, samplesPerSec, stereo)) && Stream_startSema(s, semaIndex)) { output= s; return 1; } Stream_delete(s); } return primitiveFail(); }

It's possible the

...

...

*** malloc_zone_malloc[463]: argument too large: 4294967280

is a clue, I'd check input into the sound primitives...

mmm Buffer *Buffer_new(int size) { Buffer *b= (Buffer *)malloc(sizeof(Buffer)); if (!b) return 0;

perhaps that malloc failed?

I'll note the buffer is calculated from calling int sound_Start(int frameCount, int samplesPerSec, int stereo, int semaIndex)
