Does this feature take into account the optimization level
that one may set via CFLAGS?  Conventional wisdom used to 
claim that debuggers did not fair too well with code that
was compiled with -O2 (or -Os and/or other well-known gcc
options -fomit-frame-pointer, etc.)  The common advice was
to recompile one's code with -g or '-g -O'.  Does lldb cope
better with optimized binaries?
