If those are gdb bugs, please file them.
Well I think everyone knows about the failings of gdb in -O1 mode, they
have been much discussed, and they are not really gdb bugs, more an
issue of it being basically hard to debug optimized code. Things used
to be a LOT better, I routinely debugged code at -O1, but then the
compiler got better at optimization, and things deteriorated so much
at -O1 that now I don't even attempt it.
