breaks occur where brakepoint not set LV2014

[richjoh]

I'm using Labview 64bit 2014, I have not set any break points. My VI stops on BD icons, blinking with Continue Button enabled as if I enabled a breakpoint. I must hit Continue each time. I never set a breakpoint. If I replace/remove the BD icon, the breakpoints stops at the connecting BD icon.

Is this a documented bug?

Never heard of this before.  Are you able to post the VI that shows this behavior?

Does it stop on a specific icon on the block diagram? Does this icon by any chance have a red border around it?

Sometimes it can be very easy to inadvertently place a breakpoint on a wire, icon or an entire block diagram. Right click on something like a wire the block diagram and from the Breakpoint submenu select Breakpoint Manager. this window will show you where there are any BPs set.

See the pics below, one pic show the VI Breaks on the <=0 and enables the pause/continue || button. Notice there are no red highlight over the <=0 icon, as per a normal breakpoint, its just a black blinking square when it breaks over the icon.

In the second pic I change the VI a little and break occurs on the "first call?" icon with the same blinking square over the icon. I changed it earlier and break moved to the T/F case structure.

I have no idea how to make this happen, anyhow if it happen to you now you know.

At this time does the Breakpoint Manager show anything?  I'm leaning twords the first bug of 2014 (probably not actually).

Breakpoint manager is empty of breakpoints. I know I check the breakpoint manager and didn't see any breakpoints.

Now after creating a really simple VI trying to reproduce the issue, I noticed Labview breakpoints works slightly different than before. The breakpoint point use to stop and blink on wherever the break is set, now compiler choose to STOP on the break and BLINKS on the NEXT BD icon to be run AFTER the break point. This is best seen using highlight on with wired Icons and computaton on wires.

So maybe I had a breakpoint set, not shown in the manager, and my VI breaks not the way I was expecting...

Anyhow, VI appears normal now that I change something in it, what I don't know.

This problem occurred again. Just before this happening, I connected, by branching a "Not a Number/Path/Refnum" to a probed unsigned long wire resulting in a crossed out (or invalid) probe. (Ultimately but maybe not necessary, I removed the integer wire and replaced it with a reference wire.) Once I rerun my VI, it stop on at the unknown breakpoint, meanwhile breakpoint manager show no points are setup.

To clear the hidden breakpoint, I close all the probes and whalla, mistery breakpoint gone. Wonder if anyone can replicate it or this is already documented?

Not sure if I missed anything in the previous posts, but was your probe set halt on a certain condition?

[richjoh]

"was your probe set halt on a certain condition?"

No, not a conditional probe just regular.

The Only thing I can think of is a corrupt probe or set of probes.  (BP Manager won't look in those)
