We've been through that in this thread: Miles suggested that a day or
two ago.  To which I replied that the GCC documentation doesn't give
you any useful information about which options to turn off to get a
reasonably debuggable program.  And there's no hope for anyone but a
GCC optimization expert to figure that out on her own.
