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.
