Created an attachment (id=82265) [edit]
zsnes-memfix.patch

Hi guys,

I also came across this problem after upgrading to glibc-2.4. At first I
thought it had to do with the changes regarding threads in the new glibc, but
after running zsnes through gdb I noticed that this was actually a trivial
memory corruption bug in zsnes that apparently the old glibc wasn't detecting.

Anyway, this is the patch I created to solve it; it works for me, but please
test and perhaps report upstream.

Thanks.

Your patch resolved the issue for me. Thanks a bunch, 
You should notify the zsnes devs of this issue. 

(In reply to comment #4)

Not comfortable with re-digesting my own ebuilds (yet) and using diff to patch.
 could someone handhold me at podfish at gmail dot com?

Thanks!

According to the zsnes devs, this patch is irrelevant--it's been fine in CVS
for months, and I should use that instead.  Maybe they should release, then?

yes, I would love to see them do a real release.

....so, is this patch going into portage?  does it negatively affect machines
with <glibc-2.4?

I'm suffering this problem. I don't understand what's stopping its fixing:
- There's a patch.
- There are newer versions (see 131198) with their own ebuilds.

http://www.gentoo.org/proj/en/desktop/games/#doc_chap5_sect10

Time is what is stopping it.  There's only so many of us that can do the
necessary testing and then commit the patch.  I'm sorry, but have some
patience.  We all have lives and families just like the rest of you, and none
of us are paid to do this.

works for me.  This patch has now been sent upstream.

Just out of interest, how long is this likely to take? (to become part of
portage I mean).

http://www.gentoo.org/proj/en/desktop/games/#doc_chap5_sect10

*** Bug 142233 has been marked as a duplicate of this bug. ***

Is this bug related to the "Illegal Instruction" bug? (run zsnes, says Illegal
Instruction in the terminal then exits) or is that a seperate issue?

in portage.  thanks for the bug report and patch.

right on!  Thank you for taking the time, Mr. Bones.  and thanks for the patch,
Leonardo!

Uhm, not to nitpick, but shouldn't you either bump 1.42 to -r1 or make the next
ver stable? RESOLVED FIXED is a funny state for a bug where people who already
have zsnes installed have to re-emerge manually (after they hunted bugzilla for
this, that is).
