[cfe-users] Crash reporting for inline functions

I suspect the crash reporters are giving you results based solely on the symbol table.  The dSYM has extra information from the debug info so it can fill in the gaps.  Perhaps the crash reporters aren't using the dSYMs, but Xcode is?

Any ideas Adrian?

However, when I cause the crash in the Xcode debugger, I see the inline functions in the stack trace. Is there additional context that Xcode would have, e.g. with symbols in the binary, that the crash reporters with their dSYM files don't?
