When I debug my code the debugger goes up and down (two ways) (sometimes to the begining of the method) ; in java this behavior don't appear

I have another question
when I choose display as array the array appear good but I want this behaviour to be repeated every time I debug not only for the current one .

Do you have compiler optimizations turned on for your project? When the
compiler optimizes code, it can change the ordering of instructions,
inline functions, and change things in ways that cause confusion for the
debugger.

when I debug this code

uint32 **smap;

 for (i = 0, k = 0; i < n_total; i++)
        for (j = 0; j < n_state_pm-1; j++)
            smap[i][j] = k++;

every time compiler goes to the begging of method

int32 make_mdef_from_list(char *mdeffile,
			char **CIlist, 
			int32  nciphones,
			heapelement_t **CDheap,
			int32  cdheapsize,
			char  *pgm)
{

Then you are using your own Makefile. You must tweak your Makefile to turn off optimization.

I do that and most of optimisation is disabled now , but there is some codes still optimised , my project is SphinxTrain and it is depend on sphinxbase , I think this cause the problem , I disabled optimisation in sphinxbase , but also there is some code that still show me , not optimized message

is it possible to see not optimised message even if I stop optimisation ?

Did you do a clean rebuild after disabling optimization?
