Ok, after loosing the whole day fiddling with automated test cases I could manage to produce a small test case that shows the problem.
I noticed that it only happens when:
- I jump to a different frame from within a setInterval handler
- movieclips in the target frame call a function of the parent
- that function calls another function
This would be the correct output:
-------------8<----------------------------------------------------
_level0.instance1 --> 1 =
_level0.instance1 --> 2 == / 1091
_level0.instance1 --> 3 === / 1091
_level0.instance1 --> 4 ====
_level0.instance3 --> 1 =
_level0.instance3 --> 2 == / 1091
_level0.instance3 --> 3 === / 1091
_level0.instance3 --> 4 ====
_level0.instance5 --> 1 =
_level0.instance5 --> 2 == / 1091
_level0.instance5 --> 3 === / 1091
_level0.instance5 --> 4 ====

Instead, Gnash produces this:

Code:
-------------8<----------------------------------------------------
// ### FRAME 1 ####################################################
function local_whatever() {
return getTimer();
}
stop();
setInterval(
function() {
if (_currentframe!=1) return;
gotoAndStop(3);
}
,1000);
// ### FRAME 3 ####################################################
stop();
function init_me(obj) {
trace(obj+" --> 1 =");
trace(obj+" --> 2 == / "+local_whatever());
trace(obj+" --> 3 === / "+local_whatever());
trace(obj+" --> 4 ====");
}
// ### FRAME 1 OF MOVIECLIP #######################################
_parent.init_me(this);

The compiled SWF file is attached.
I could not make a swfc-based Testcase as I don't know how to define
movieclips.
Zou suggested to remove ActionExec.cpp:470:
- VM::get().getRoot().flushHigherPriorityActionQueues();
This helps in this specific case but brings up other problems.
However, these other problems may be because of a buggy gotoAndPlay()
implementation, as Strk says (setting PLAY state after the jump).
I don't know enough about our VM to judge what is correct.
So, please, if someone can help me get this fixed I would greatly
appreciate. This bug is making me loose much time on a already
mission-impossible-timeline :-/
Thanks,
Udo
