Another data point...
If I use atos against an application built with DWARF I get correct
symbol names and correct line numbers.
If I use atos against an stripped version of that same application
that has an associated dSYM file (generated using dsymutil) I get
incorrect symbol names (always states "operate new(unsigned long,
void*) instead the name of the objective-c method) but I do get
correct line numbers.
If I use atos against an unstripped version of that same application
that has an associated dSYM file (generated using dsymutil) I get
correct symbol names and correct line numbers. Likely because the
application still has the full DWARF symbols in it (likely doesn't
even bother with the dSYM file).
I will switch Xcode to build using DWARF with dSYM next (avoid using
dsymutil) to see if that corrects things for us.
Note it looks like our build script got changed from saving the
unstripped application and related dSYM to saving the stripped
application and related dSYM. So my prior post was incorrectly stating
how we build things.
