Under certain circumstances, the curses function addstr() will cause a segfault in python3.2.3 and python2.7.3. Necessary, but not sufficient conditions are: 1. the window has been resized while curses was running 2. addstr() attempts to write a string that doesn't fit into the window, resulting in the cursors y-position being outside of the boundaries (which would normally only raise a _curses.error) Instead of the "Segmentation Fault" message, I also sometimes get one of these two messages when python crashes: *** glibc detected *** python2.7: corrupted double-linked list: 0x0949cc98 *** python2.7: malloc.c:3964: _int_free: Assertion `nextchunk->fd_nextsize->bk_nextsize == nextchunk' failed. To my shame, I didn't try to debug python myself, and I can't offer a minimal program to reproduce this bug, but I did find a way to reproduce it in the python program "ranger": Link to the bug in rangers bug tracker with steps to reproduce: https://github.com/hut/ranger/issues/45 Download link to the affected version of ranger: https://github.com/hut/ranger/tarball/5ee1e874cc5f9136af3a9a835b76076a85693bd0 |

> I can't offer a minimal program to reproduce this bug, but I did find a way to reproduce it in the python program "ranger" Sorry, but without a smaller example program, I cannot help you on this issue. Please try to write a smaller program to reproduce the crash. |
