#560 Loop skipped by a single Step Into

[Jan Ploski]

First reported here: https://sourceforge.net/forum/forum.php?thread_id=3362178&forum_id=258688

The problem seems to be that Step Into continues execution until the instruction pointer has changed, but the debugger ends up on the same line after the step in the example case:

for ($i=1; $i<5; $i++)
{
print $i."\n"; # cannot single-step over it
}
