Xbox One gamepad crashes with Floating Point exception 8 error

Hi all,

SDLMame is crashing in my mac if i connect an Xbox One bluetooth gamepad with this error: Floating Point Exception: 8.
I tried to get more debug info about the crash using "-verbose" but no relevant extra info appeared. This Xbox gamepad is model 1708 and it connects via bluetooth and does not require an additional driver.

At the end of this post, i attached the crash log / backtrace that shows in the apple finder when the exception happens.

I´d like to ask to some experienced user if is there any config suggestion or some method to gather some additional information about. My gamepad works well with other games.

My system:
Official SDLMame 0.205 with symbols file "mame.sym"
OSx Mojave 10.14.2
Installed Libsdl 2.0.9 in /Library/Frameworks

Here are linked the verbose info in the terminal and the crashlog that apple creates:
Verbose log: https://justpaste.it/32qq7
Crash: https://justpaste.it/2ijx4

Thanks in advance

Re: Xbox One gamepad crashes with Floating Point exception 8 error

This bug is related to current stable libsdl v2.0.9 version.

I compiled SDL2 from current GIT source and now SDLmame for mac does not crash and gamepad works perfectly.
So in the end this bug was not related to Mame itself... :oops:

The good thing is that in the next SDL2 version this bug is going to be fixed.
