GuardMalloc error UITextView

[mebarron]

This has worked for me for weeks.
I click on a touch above my TextView and reach this code

- (void)textViewDidBeginEditingUITextView *)textView
{
1 [cancelButton setHidden:NO];
2 [saveButton setHidden:NO];
3 textCopy = myTextView.text; //save for CancelButton
}
There is a break on line #3, I go to gdb and issue the po command you see below
(gdb) po [myTextView text]

I received the following error message

Previous frame inner to this frame (gdb could not unwind past this frame)

I then turned on GuardMalloc and now see the following in Debugger Console:

(gdb) po [myTextView text]
Unsafe to call functions on thread 5: function: GMmalloc_zone_free on stack
Target does not respond to this message selector.

I do use sqlite3. I understand I need to change things before release in 3.0

This is my first app. Thanks for reading.

Any advice? Many Thanks, Mark

In the debugger I see in the GuardMalloc run
at one point I saw
#0 0x007b31c6 in mach_msg_trap
#1 0x007ba9bc in mach_msg
#2 0x007d7c29 in vm_deallocate
#3 0x000104e2 in GMmalloc_zone_free
#4 0x000108fd in GMfree
#5 0x00104483 in sqlite3CreateIndex
Now I am seeing
