FWIW, it's still broken in Snow Leopard :-(.  Stack trace is

(gdb) bt
#0  0x0000000100097ccc in re_putc ()
#1  0x00000001000981f6 in re_refresh ()
#2  0x0000000100097b67 in el_gets ()
#3  0x00000001000a49b6 in readline ()
#4  0x000000010000856f in gets_interactive (prompt=<value temporarily unavailable, due to optimizations>) at input.c:76
#5  0x0000000100008b8b in MainLoop (source=0x7fff701140c0) at mainloop.c:132
#6  0x000000010000b14f in main (argc=<value temporarily unavailable, due to optimizations>, argv=0x7fff5fbff5f0) at startup.c:285
(gdb) 

which pretty conclusively puts the blame on libedit.  This isn't the
first libedit bug report we've seen, either.
