Bug 106953 – zsnes: crash/segfaulting when trying to change video mode

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Jeff 2005-09-22 22:19:34 UTC]

Zsnes 1.42 emerges fine, but lots of problems:

When clicking the game -> load button or sometimes when starting zsnes (not
always, about 2 times out of 5), it crashes with either of these 2 errors:
*** glibc detected *** malloc(): memory corruption: 0x085e1470 ***
Aborted

or this:
*** glibc detected *** free(): invalid pointer: 0x085e1470 ***

Also, when I try to change the video mode, zsnes freezes. If I wait a few
seconds before killing the window, I get this message on the shell:
Fatal signal: Segmentation Fault (SDL Parachute Deployed)

Here is an strace: http://pastebin.com/371695
It should be noted that the same segfault happens every time when starting zsnes
without doing anything else, then a new prompt is displayed with the normal
Zsnes messages getting displayed starting at line "$ ZSNES v1.42 (c) 1997-2005,
ZSNES Team" (don't know much about straces but that's first time I see this), so
I couldn't get an strace at the time of the "sdl parachute" error.

Reproducible: Always
Steps to Reproduce:
1.Start zsnes
2.Try to change video mode



Expected Results:  
Be able to change video mode without zsnes crashing, and possibly not getting a
segfault when starting it.

Can you try zsnes 1.5.1?
