IMO, by turning CONFIG_DEBUG_INFO=y, you actually disable the gcc

optimization (plus enabling the -g option). Or at least, you can
always do it by manually edit the CFLAGS.
Actually CONFIG_DEBUG_INFO doesn't disable optimizations, I noticed that some times the frame pointer and certain local variables are optimized away and this gives unexpected results while debugging. What I do is I put "-02" in CFLAGS_REMOVE and "-O0" in CFLAGS to make debugging give expected results
