In tty.c in libedit, the function tty_bind_char() has a bug. Line 759
should be changed from:
char new, old;
unsigned char new, old;
This is because new and old are used as an index to a command
array, and gets assignments from an unsigned char. When 255 gets
assigned to them, it gets converted to -1 which is out of bounds.
This leads to a segfault when trying to exit the test program test.c
included with libedit. If I can be any further assistance with this
bug, please to not hesitate to ask.
