Are object files built with -O3 (-finline-functions) debuggable at all?
The user might not be able to get a usable backtrace from a core dump,
even if debugging symbols are availbale. (A core dump may be the
consequence of SIGQUIT, not just SIGSEGV; or he/she may choose to run
the program under gdb, or attach gdb to the running program.)

If -O3 objects really are non-debuggable, does that mean that Debian
will move into a direction where
a) all packages are at most -O2?
b) all -dbg packages include -g3 -O0 binaries, and X-dbg conflicts with
X? (Or are all -dbg binaries named -dbg?) What about Heisenbugs? What
about libraries? Can a user select (via ld-linux.so) the
debugging/stripped version of each library?
