snes9x-gtk: Crash at startup

[YuGiOhJCJ]

Hello,

After I built snes9x-gtk from snes9x-1.53 on Slackware 14.1, I try to launch it:

Code: Select all

$ snes9x-gtk 
Sound buffer size: 4096 (1024 samples)
OSS sound driver initializing...
    --> (Device: /dev/dsp)...failed
Attempt to unlock mutex that was not locked
Aborted

So, I check with my debugger:

Code: Select all

$ gdb snes9x-gtk

Quit anyway? (y or n) y

Do you know why I got this error?

Thank you.
Best regards.

After some researches, I found that it is a problem with the strict mutex behavior in glib 2.42 [1].
Maybe I should try to downgrade to glib 2.40 to see if it solves the problem.
Anyway it should be a good idea to see how to hack correctly the snes9x-gtk source code to be compatible with the new glib 2.42 stable release, isn't it?
