[Matplotlib-users] Intermittent Matplotlib crash on OS X

[Anand P. <an...@so...>]

Hi all,

Matplotlib occasionally crashes Python at the end of a long program on 
my powerbook g4 running OS X 10.4. gdb output follows:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x0a68fe40
0x002eae50 in visit_decref (op=0x28a1cb0, data=0x0) at 
/Users/ronald/Python/r25/Modules/gcmodule.c:270
270     /Users/ronald/Python/r25/Modules/gcmodule.c: No such file or 
directory.
        in /Users/ronald/Python/r25/Modules/gcmodule.c

or

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000056
0x002eae50 in visit_decref (op=0x28a17e0, data=0x0) at

It's always something like that, and it always happens after the little 
Python icon starts bouncing around in the dock. I don't know anyone 
named Ronald and no such directory exists on my machine.

Thanks,
Anand Patil
