V interaktivnom mode simulator sposobi segmentation fault pri ukonceni
vystupu (napr. Ctrl+D).
Problemovy kod (machine.c):
286
287 if (*commline) //<--tuto
288 interpret( commline, -1);
289 else
backtrace:
#0 0x0804d384 in interactive_control () at machine.c:288
#1 0x0804d487 in go_machine () at machine.c:345
#2 0x0804da1f in main (argc=0, args=0x0) at main.c:152
(gdb) p commline
$3 = 0x0 <--- na riadku 287 sa dereferencuje NULL pointer
Este jedna drobnost: pri kompilovani som si musel rucne v src/Makefile doplnit
LIBS = -lreadline -lcurses (povodne bolo len LIBS = -lreadline),
pretoze to nechcelo zlinkovat (pravdepodobne treba nieco zmenit v
configure).
