New submission from Lukas Lueg:
IDLE crashes due to what seems to be a use-after-free bug. Opening a file from
the 'Open...'-menu leads to a segfault after the text has been rendered. It
seems this can be reproduced 100% of the time if the file is big (e.g. 150kb)
and the window receives events (clicks...) while the colorization is going on.
I've been able to reproduce this behaviour on MacOS 10.6 (3.2, 3.3 and 3.4a)
and Windows 7 (3.3) but not on Fedora 17.
Python 3.4.0a0 (default:a728056347ec, Nov 23 2012, 19:52:20)
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin
I'll attach a backtrace and a malloc_history (from a different trace). Any
guidance on further debugging on this?
