[BUG]Squeak VM mac 3.8.18beta1U

When I hit the record button in RecordingControlMorph two times after
each other, the image just disappears, no debug log.

I have no mic on the machine.

I'm on mac os x 10.3.9

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.

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)
