What does Trace/BPT trap: 5 mean, when a Mac OS X application suddenly exits?
Searching the web I only found out that a lot of applications exit like this (ruby, postgres) but only find application specific solution. But I want to understand what that is and how it is caused.
I also found that it seems to be an issue on Mac OS X only (did not find any mentions of this happening with Linux or Windows). I believe it has something to do with threading, but I'm not sure about that one.
It has to do with not being able to find/load a dylib, which is specific to OSX.
Which one it can't find, is as you have found out is application specific.
