Segmentation fault when loading games

[ghost]

I have recently upgraded my operating system to the beta version of OS X Yosemite. Since then, I am unable to join games or open games in the studio: every time I attempt to open or play a game, ROBLOX crashes immediately.

When a game is played through a command given to the terminal application (e.g. /Applications/Roblox.app/Contents/MacOS/RobloxPlayer --id 1818 to play Crossroads), ROBLOX gives the following messages:

Is it possible that you could provide the opcodes located at 0x01b569d1? I would assume it has something to do with ecx and it's causing this error.

[The0neThe0nly]

Also, is it possible you could send me some kind of minidump-like file where I could browse the crash myself? I haven't used mac in ages and I have no idea how their crash reporting system works.

On @zeux's suggestion, I have set the SoundEnabled setting to false (I believed it was already set to false, but it seems it has been reset after some update, or for some other reason). This has fixed the problem.

I have closed the issue, although the problem is only fixed on my end, because we now have a solution and all the useful information has been gathered here. Furthermore, @zeux does not have the problem on Yosemite, so it may be difficult to figure out the cause of the problem, and there is no clear way to reproduce it. If however someone thinks it should be reopened, which would be reasonable as well, I guess I will reopen it.
