Mac Crash Report - Obfuscated methods

General
1

Hi Forum

This one is probably more for the Xojo team.

I have spend a lot of weeks now trying to get rid of some hard crashes, but I still can’t figure this one out.

Is it possible for someone at Xojo to point to what the “attached” obfuscated method names could be, to help me get in the right direction?

they’re not obfuscated - the names literally don’t exist so all the crash reporter can tell you is “it died in the rbframework.dylib at a spot this far from the beginning of the file”

your best bet is to file a feedback report with the crash log attached stating what version of Xojo your using & even a sample project if you can

I will do that, thanks.

Just out of curiosity: what will the crash-report help if the method names can’t be resolved?

The crash isn’t so much obfuscated as it is lacking symbols. Internally we have a symbol server that lets us take the address and map it to the actual file/line/revision.

Ahhh, thank you :slight_smile:
