It's a serious bug in the S-Lang library.  Function send_attr_str
overwrites the stack and then crashes:

Program received signal SIGSEGV, Segmentation fault.
(gdb) where
#0  0x080a9b6e in send_attr_str (s=0xbfff0073) at sldisply.c:1470
#1  0x71717171 in ?? ()

Since mc includes some files from S-Lang, it would be nice to fix at least
our code.  If the limitation is hard to remove, the sanity check in
slint.c (slang_init) should be made stricter to exit gracefully rather
than crash.
