Summary: Segmentation fault with invalid "coding"
Initial Comment:
Reproducing the bug:
1. Create a file with a invalid encoding such as:
# -*- coding: utf-8i -*-
2. Run it:
python wrong_coding.py
3. Enjoy your segfault... :P
Versions tested:
- Python 2.4.2 (Ubuntu Breezy)
- Python 2.3.5 (Debian Sarge)
Running it directly with "python -c" gives MemoryError. Strace output:
# strace python -c "# -*- coding: utf-8i -*-"
(lots of searching through modules...)
open("/usr/lib/python2.3/site-packages/ZopePageTemplates/utf_8i.
pyc", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or
directory)
write(2, "MemoryError", 11MemoryError) = 11
write(2, "\n", 1
) = 1
rt_sigaction(SIGINT, NULL, {0x400297a0, [], SA_RESTORER,
0x400c16f8}, 8) = 0
rt_sigaction(SIGINT, {SIG_DFL}, NULL, 8) = 0
exit_group(1) = ?

Are you sure you can reproduce with 2.4 CVS branch. I just
fixed this recently (Fix segfault with invalid coding. in
Misc/NEWS). I can't reproduce on 2.4 CVS. I expect this
probem exists in 2.4.2 and earlier. Checked in around
2005/10/02 at 01:48:49, bug #772896.
The memory error was fixed in CVS, but not backported.
That's up to Anthony (release manager).

Reproducable here with 2.4.2 and the 2.4 CVS branch. It
seems fixed in HEAD.
