you're not freeing everything you allocate with malloc().
XS-file (created by command "h2xs -A -n Smai"): http://genphys.phys.msu.ru/~dmitriyk/Smai.xs
// ym-channel matrix ym = malloc(h * sizeof(*ym)); for (i=0; i<h; ++i){ ym[i] = malloc ( w * sizeof(**ym)); } // smai ym matrix sym = malloc(h * sizeof(*sym)); for (i=0; i<h; ++i){ sym[i] = malloc ( w * sizeof(**sym)); } [omit a bunch of processing] free(ym); free(sym);
you're allocating a pair of two-level data structures, but only freeing the outer layers, and leaking all the memory for each row.
add
for (i = 0; i < h; h++) {
free (ym[i]);
free (sym[i]);
}before freeing ym and sym.
