Uh, his suggestions were av_leak_malloc(size,__FILE__,__LINE) and
memwatch, valgrind was mine. I was arguing that the suggested solutions
are worse than the existing once, including gdb.
And I have seen more cases where removing -fomit-frame-pointer hindered
debugging (due to hiding bugs) than where it helped, so I consider that really
bad advice. Inlining is far more of a issue for debugging IMO.
-g3 is advisable though.
