Description Oleg Drokin 2002-07-07 10:50:23 UTC

Midnight commander segfaults when trying to copy certain files using internal
copy or move operations.
The pattern is not yet clear, while I am able to copy files off mounted CD
without problems,
copying e.g. netscape plugins to other place on the same partition segfaults.
Here is the backtrace, and actual core file is available if needed.
# file core.15022

Comment 1 Michael Schwendt 2002-07-14 11:00:14 UTC

Confirmed. I cannot seem to copy any files at all in "mc", especially not from
mounted CD.

My test-case is as simple as opening a virtual console (e.g. ALT+F1), starting
mc, going into /etc, selecting /etc/fstab, pressing F5, and pressing RETURN.
Gives a segmentation fault always.


Since I see a possibly screen-oriented segfault also in "jed", and both mc and
jed are linked against libslang-utf8.so.1, maybe that's a common bug.

Maybe a UTF-8/slang issue?

Comment 3 Oleg Drokin 2002-07-16 13:01:01 UTC

After I upgraded mc package to mc-4.5.55-9 from rawhide, segfaults disappeared
and everything seems to be working now.
