Invalid function pointer called with signature 'vi' => 147

Unity Engine
1

Getting this error on a WebGL build via v5.3.6p1:

Invalid function pointer called with signature ‘vi’. Perhaps this is an invalid value (e.g. caused by calling a virtual method on a NULL pointer)? Or calling a function with an incorrect type, which will fail? (it is worth building your source files with -Werror (warnings are errors), as warnings can indicate undefined behavior which can cause this).

Then 147 (error code?) is spit out.

Looks like it may happen on clean up of a collider of some sort?
Ive tried to see if an asset is using a component that is being stripped out but have had no luck determining the issue. Any help would be greatly appreciated.

This looks like a bug. Could you file a bug report with a repro case, and post the case number here?

3

I was afraid you’d say that. :frowning: It looks like it happens when downloading assets via assetbundles but I can’t seem to pinpoint it to a specific asset. Ive also noticed other error “codes”: 147, 150, 163, etc. Do these represent something I can investigate?

It will take some work to package up the project for a repro but I will do my best.

4

No, these numbers are pretty much meaningless, unfortunately.

Jonas,

Unfortunately, providing this project just isn’t practical at the moment.

After about a day of investigation, it seems to come down to that CreatePrimitive(…) call. We simply create a primitive plane for objects as they are downloaded/instantiated via assetbundles and in combination with some other functionality, we receive the error I provided. This probably seems obvious based on the stack trace but we had to test various primitive types and exclude the call altogether to confirm. Unfortunately, that’s all the info I can really provide on this.

FWIW, instantiating a prefab of the object (instead of using CreatePrimitive each type) has solved the issue in WebGL.
