So an interesting exercise to confirm this would be to link with static libraries and see if I can step through the program then. What is the configure option to do that? 'CFLAGS=-g -O0 LDFLAGS=-static' doesn't work. Assumng that what you say is true, and I am not doubting you here, that would mean that 
the step function is unreliable at best. Unless you keep track of what causes dynamic libraries to be loaded, you never know when a step will execute a Continue command. I will have to stick to using breakpoints.
