Follow-up Comment #5, bug #16195 (project wesnoth):
some wml to reliably reproduce the issue:
[event]
name=prestart
{VARIABLE i 1}
[/event]
[event]
name=advance
first_time_only=no
{VARIABLE_OP i add 1}
{VARIABLE unit.experience $unit.max_experience}
[unstore_unit]
variable=unit
[/unstore_unit]
[/event]
[event]
name=moveto
{DEBUG_MSG $i}
[/event]
In 1.8 it leads to a crash without error message after lots of recursions; in
1.9 a lua error is displayed with stack overflow - good output, exactly the
one I would expect since it's like a recursive function without break
condition. In any case, the wml author does something dreadfully wrong here
so I suggest closing it as won't fix.
