Re: [E-devel] edb SEGV under sparc-solaris 2.8
Here is the part that makes it bug :
#define SHALLOC_FRAGMENT 32
/*
* If there are at least SHALLOC_FRAGMENT additional bytes of
* memory, divide the chunk into two chunks.
*/
if ((u_int8_t *)rp =
(u_int8_t *)elp-links + SHALLOC_FRAGMENT) {
sp = rp;
//--- This instruction crashes -
*--sp = elp-len -
((u_int8_t *)rp - (u_int8_t *)elp-links);
//--
elp-len -= *sp + sizeof(size_t);
return (0);
}
So what do we have :
rp = 0xff281794 -- (u_int8_t *)rp = "Cannot access memory at 0xff281794"
sp = 0xff281790 ('--sp' is applied) -- (u_int8_t *)sp = "Cannot access
memory at 0xff281790"
(u_int8_t *)elp-links = -1 : i think it's ok.
elp-len = 51008
So i guess the problem is first evaluating (u_int8_t *)rp, this pointer
is not correct.
I have already heard that etox is being deprecated and replaced by
evas_text_block, and i totally agree with the fact that it's a really
minor issue ; you have many other priorities before that, and i can live
without it begin corrected (yes i can ! ;-)).
If i have some free time, i'll try to correct it by myself. Don't waste
your precious time ! There are ever-growing TODO lists to deal with, i
guess you're not bored. :-p
Thanx for your answer. And for the hard work.

Hi everybody ;
just for fun, i tried to compile the EFL in userspace on a SunBlade150
with Solaris 2.8.
I got everything compiled and installed ; but i get a segfault on
__edb_shalloc when i try to use an etox-based application, such as
etox_test or ewl_test.
to be honest - we are working on deprecating etox - and thus edb will become
used less and less. it's already almost unused. :) that means it's likely not
worth hunting this bug down as 1. we don't run solaris and don't see the bug -
and if we don't see it, we can't easily hunt it down, and even if we do.. our
"Fixes" wont be useful for long :( if you can get us more gdb info that'd be
useful (listings, printings of the variable values etc.) as we need those to
have a better idea of whats going wrong (eg is sp NULL? or what?) :)
Here is a backtrace with etox_test :

I know i'm not in the optimal conditions for testing, but maybe it will
help to find a new bug.
Thanx in advance.
