It'd be nice if we could figure out what "some reason" was, and/or why gdb 
won't set breakpoints on these labels. Last time I brought this up I was told 
that user labels should not effect the optimizers. IMHO labels should not 
affect code quality, and this is an optimizer bug.

Marking them as artificial seems a reasonbale short term workaround.
