Original submission:

MC hangs for me if I change directories, either by selecting one 
from the panel or cding from the shell. This does not happen if it 
is started as root. I'm using Arch Linux i686 and I tried with 4.6.1
and with cvs. Another Arch user reported the same problem several 
years ago but never reported a fix.

Comment 1 by Pavel Tsekov <ptsekov> at Sun 09 Mar 2008 10:57:37 AM UTC:

Does it happen for every directory or only for certain directories ?
Could you point me to the original bug report ?

The original thread is here: http://bbs.archlinux.org/viewtopic.php?id=5469

It doesn't say much more than I already have I'm afraid. It hangs 
for every directory. Everything else appears to work fine.

It looks like it only hangs on local directory changes, I can use 
the ftp and zip VFS fine.

Under Mac OS X 10.6 this started to happen a lot. Sample trace attached.

I have exactly the same problem (stack trace is the same). I reproduce it by pressing and holding Tab button. After 20-30 seconds of switching between panels mc hangs.

I have use_persistent_buffer = FALSE set in src/subshell/common.c as otherwise mc startup is unbearably slow. The hangs are unpredictable, most of the time changing directory works, but sometimes it just hangs.
