I think a macro was used, so if you do the following, it'll break:
if (test)
FREE(ch);
ch would be freed if (test) is true, and ch set to NULL reguardless...
Maybe the macro needs braces around it or something if you want to do it that
way. Or write you own free and pass the address of the point so you can clear
it. Something like this, maybe? (not sure)
void *my_free(void *ch)
{
free(ch);
return ch = NULL;
}
Then change all your free calls to:
ch = my_free(ch);
