Ouch... I got it, it indeed was a beginner mistake. Looking through GCC to see how it used these hash tables, I noticed the problem. Sorry for the noise!
PS: for posterity, the error was: > /* Register this allocation. */ > a = (allocation_t *) htab_find_slot (tab, p, INSERT); > a->p = p; > a->file = file; This should have been: allocation_t **a; /* Register this allocation. */ a = (allocation_t **) htab_find_slot (tab, p, INSERT); *a = malloc (sizeof (allocation_t)); (*a)->p = p; (*a)->file = file; and later accordingly. -- FX Coudert http://www.homepages.ucl.ac.uk/~uccafco/
