Failed loading application - class limit of 32?

I added a couple new classes to a fairly complex application and started getting "Failed loading application" in the simulator. I removed them and tried adding just a simple empty class. Same thing. Is there a limit to the number of classes (not objects) you can have? I'm using about 107k of my 122k limit for an application on my 935 so memory shouldn't be the issue. I'm not even creating an object, yet, based on this class, so number of objects shouldn't be the issue. If I counted correctly, I'm at 32 classes before adding these. That's a pretty suspicious number in terms of a likely limit.

I'm not getting any kind of compiler warning. App just won't run in the simulator or the watch.

In the sim, under view memory, what does your object counts look like without the new class? There could be a limit of 32 classes, but I've never heard of a problem with that before.

I just tried and added 32 (empty) classes to a simple watchapp, which makes it actually 34 classes, no problem with that...

Definitely a class issue as it loads fine if I comment out a couple other classes that don't initially get used. With over 32 classes, it doesn't even execute the initialize on my AppBase object.

Memory usage: 108.1/122kB
Peak Memory: 110.6kB
object Usage: 148/512
Peak Objects 160

Looks like it is some kind of global symbol limitation.

I created a new CIQ app without modifications. Then added a bunch of classes. It started failing at 145 empty classes as in "class a0 {} class a1{} ..."

Only adding 144 works. But then if I create a global variable as in "var i;" it fails. Adding a variable to an existing class is fine.

Not sure exactly what all goes against the limit. Most of my objects and variables are inside of other objects, such as a global "state" object.

Hey,

I was doing some work on this yesterday too and couldn't reproduce. The extra info about the global var at least gives us a lead on where to look. I'll try and see what we can find out today.

for whatever reason, adding a Link to the message cut off everything after the domain name so here is the correct link

Perfect! Hoping to get this figured out today.

Seems like it is any global symbol: function, class, const, enum. Adding any of the following to my code also causes the failed load. The enum below actually takes up 3 global symbols. That definitely helps explain how in my original application I reached this limit as I have a fair number of const's and enum's.

var i;
function a(){}
const a=5;
enum {x,y,z}

Did you ever look into this in more detail? Is there a global symbol limit that is being hit?

Hey,

We were able to take some time to look at it. Though it is not fixed yet, it is scheduled to be fixed in a future release.

Thanks,
