App crashing on startup issue

First time back on this forum for a while, very nice new forum :smile:

So my old app is crashing on startup for some people (mainly iPad 1) and I am looking to fix this issue.

Here is the crash log:

Stepping downwards, what is likely to be the culprit here? ofColor? ofEventI11buttonEvent? ofToString?

Any thoughts greatly appreciated.

p.s the app was made in OFW 0.80, just upgrading to 0.84 to see if it helps.

Thanks

Looks like ofColor was the last call, which is using a ofVec3f to determine the color value.

Can you debug directly with the iPad1?

Just a note: iPad1 has very minimal RAM, so can crash in random places due to memory allocation fails.
