To me it sounds like the terminal's been reset to line mode.  Type  
"tty" to the shell before starting ghci (it will output something  
like /dev/pts/3 or /dev/ttys003 or /dev/ptyp3), then when the problem  
happens switch to another terminal and type "stty -a </dev/pts/3 |  
grep icanon" (substituting the output of the "tty" above).  Look for  
"icanon" or "-icanon"; the former is line mode, the latter is  
character mode (ghci's readline requires the latter).

This won't help you solve it but at least gives you some information  
to put in the bug report.
