  • Thread-topic: Trapping Console Messages

I'm not using any of the templates.  I was just hoping if I could find out
wats generating those messages, maybe it would be related to the craches I'm
having.

I have a data hierarchy window that opens with the document.  It is two
tab-views deep with tabs mostly containing NSTableViews.  Two of the
messages show up after that window is made key and ordered front.  Then I
have a choice of main presentation window: Scrolling-zoomable; non-scrolling
resizable; borderless full screen.  The nibs have only minor differences.
Launching the scrollable window results in four more of those messages.  I
can switch between window type.  This works for a few times, then crashes.
Even if I keep the same type window and close/open it a few times, it
crashes.  I'm not getting much that is source readable in the stack trace.
Those same nibs won't even load under an unnamed operating system.  I was
hoping that would yield some more clues as to what is going on here.

Putting a break on malloc_printf gave the following stack trace for the
messages:

#0    0x94b0c943 in malloc_printf
#1    0x96c28a6c in auto_collect_internal
#2    0x96c28b8f in auto_collection_thread
#3    0x94a5c095 in _pthread_start
#4    0x94a5bf52 in thread_start
