100% CPU and growing memory usage when enters directory "foo [bar]", hangs when exits

[livibetter]

If there is a directory name with square brackets, e.g. foo [bar]

mc will consume entire CPU and continuously use more and more memory if enter such directory. In htop, it looks like

/usr/bin/mc -X
 `- bash -rcfile .bashrc
   `- bash -rcfile .bashrc

The last one process is the one consumes CPU and memory. Normally, it should have one bash. Somehow, it is spawned when enter that directory.

If exits the directory to upper directory, mc will hang.

Killing that bash can resolve the hangup.

If run mc --nosubshell, the problem won't show.

I found out it's about my bash prompt (in .bashrc). So this has nothing to do with mc. Sorry for this invalid report.

Thanks for the update. Closing then (I think you have enough privs to close your bugs too).
