how it looks in gdb:

on step 5 we turn out in src/main.c
in function endwin from curses library.

Its call cause segfault.

Unfortunately, bug appear time to time.

PS 
In latest snapshot of mc 4.6.1 from RH there are no such bug.

I had same bug. To fix it I update slang library to the slang-1.4.9-r2.

[Comment 4 Jakub Moc (RETIRED) 2006-04-17 12:33:44 UTC]

Please, try w/ mc-4.6.1 and latest slang (Bug 122768) and report back.

Uhm, damned paste. I meant:
