Ok, I see now. Makes sense. Changing the example code to:
char *a = malloc(strlen(PARSE_STRING)+1);
strcpy(a,PARSE_STRING);
rl_parse_and_bind(a);
works indeed. Thanks for the quick reply :-)

It depends on the behavior of your compiler. rl_parse_and_bind wants to
modify the string it's passed by temporarily putting in NULs and later
restoring the original characters as part of tokenizing the line, similar
to strtok/strsep. If your compiler puts string constants into read-only
memory pages, you'll get a seg fault if you pass such a string constant to
rl_parse_and_bind.
