Description
I stumbled upon this error when mc segfaulted when tried to open/enter archive.
Turned out the archive was deleted in other terminal but still was on the screen of mc in the first one.
Same crash happens with zip, 7z, rar but not with tar. The latter shows error box: \`Cannot open tar archive\n /path/to/file'.
To reproduce one needs to put archive (any, but tar) somewhere, switch to another terminal and delete that file. Then switch back to the first mc and enter the archive.
According to gdb it happens in extfs_open_and_read_archive() function (log attached).
