> May be there is a difficulty with free_all_bufs() ? > If i understand well the foreach() function : Hi Olivier, As it turns out, the "foreach sig -g" can be accomplished in a much easier manner by using crash's built-in hq_xxx() hash queue functionality. So there's no need to (1) pre-allocate anything, or (2) re-invent the wheel by creating a new hashing function. Anyway, I've got the "foreach sig -g" piece pretty much complete -- so I'll take it from here.
