Hello everyone, I have a user reporting a crash whenever they try to first save a file. It is reproducible for the user (though not be me) and I'm wondering how to best debug this problem remotely. I've included the crash stack below (all other threads are waiting/trapped).
I'm no expert on dyld, but I suspect the crash is triggered when loading up some bundle code required by OSX's save panel (or perhaps some kind of installed system enhancer). I've discovered the environment variable DYLD_PRINT_LIBRARIES_POST_LAUNCH, which I'm hoping will help identify the relevant library. However, my fear is that this debugging aid logs each library's path only after each load completes successfully (ie: conceptually after the crash). If so, that obviously won't help me.
