Here is the part that makes it bug :
(B
(B#define SHALLOC_FRAGMENT 32
(B/*
(B* If there are at least SHALLOC_FRAGMENT additional bytes of
(B* memory, divide the chunk into two chunks.
(B*/
(Bif ((u_int8_t *)rp >=
(B(u_int8_t *)&elp->links + SHALLOC_FRAGMENT) {
(Bsp = rp;
(B//--------------- This instruction crashes -------------------------
(B*--sp = elp->len -
(B((u_int8_t *)rp - (u_int8_t *)&elp->links);
(B//------------------------------------------------------------------
(Belp->len -= *sp + sizeof(size_t);
(Breturn (0);
(B}
(B
(BSo what do we have :
(B
(Brp = 0xff281794 --> (u_int8_t *)rp = "Cannot access memory at 0xff281794"
(B
(Bsp = 0xff281790 ('--sp' is applied) --> (u_int8_t *)sp = "Cannot access
(Bmemory at 0xff281790"
(B
(B(u_int8_t *)&elp->links = -1 : i think it's ok.
(B
(Belp->len = 51008
(B
(BSo i guess the problem is first evaluating (u_int8_t *)rp, this pointer
(Bis not correct.
(B
(B
(BI have already heard that etox is being deprecated and replaced by
(Bevas_text_block, and i totally agree with the fact that it's a really
(Bminor issue ; you have many other priorities before that, and i can live
(Bwithout it begin corrected (yes i can ! ;-)).
(B
(BIf i have some free time, i'll try to correct it by myself. Don't waste
(Byour precious time ! There are ever-growing TODO lists to deal with, i
(Bguess you're not bored. :-p
(B
(BThanx for your answer. And for the hard work.
