Incorrect behaviour
% mame
zsh: segmentation fault mame
Mame crashes with a segmentation fault only if the joysticks are connected.
With only 1 joysticks connected I was able to run mame, scroll to some games and as soon as I launched them they crashed. I was able to play super mario bros (vs) and pacland (for like few seconds though). Then I also had a seg fault. With two joysticks attached it doesn't even start (see above the terminal output).
With no joysticks attached it runs perfectly.
Expected behaviour
Mame doesn't crash and I play my games happily with my friends and we use joysticks!
Steps to reproduce
cd ~/mame mame --> seg fault if joysticks are connected
Additional details
I've installed mame 0.258 with brew.
Is the SDL2 version up to date in brew? There were known issues with joysticks crashing in earlier versions.
it's .258 but doesn't show from which commit.
I'm building from source right now, let's see
I've build from git. I get the same results:
first try on usb->usbc adapter
matt@Matts-MBP mame % ./mame
objc[93149]: Attempt to use unknown class 0x600001c54270.
zsh: abort ./mame
# no joystick
matt@Matts-MBP mame % ./mame
Average speed: 99.70% (40 seconds)
2nd try on mac original usb -> usbc converter
matt@Matts-MBP mame % ./mame
zsh: bus error ./mame
matt@Matts-MBP mame % ./mame
zsh: segmentation fault ./mame
back on the first adapter
matt@Matts-MBP mame % ./mame
zsh: segmentation fault ./mame
Is there something special to add when building? I just ran make (after installing sdl)
The question is whether the SDL2 framework is up-to-date. What exact version of SDL2 do you have installed?
Yes. "brew list sdl2" will show the installed version. On my system, I get "/usr/local/Cellar/sdl2/2.28.3/bin/sdl2-config", meaning I have 2.28.3, the latest.
I also get the same from brew.
/opt/homebrew/Cellar/sdl2/2.28.3/bin/sdl2-config
I didn't know I had it from brew, so before building I've download and installed the latest one from the sdl2 website into /Library/Frameworks/. That's also 2.28.3.
`matt@10-0-0-38 mame % otool -L mame | grep SDL
@rpath/SDL2.framework/Versions/A/SDL2 (compatibility version 2801.0.0, current version 2801.3.0)`
Ok. Can you run MAME with -verbose and paste the part of the output where it's setting up the joysticks? We've had repeated issues with cheap junk that sends invalid things according to HID specs and needs to be filtered out. Real Sony/MS/Nintendo pads work fine, of course.
Also if you could get a backtrace that would be great. You do that like this:
- lldb mame (this takes a minute the first time, you'll probably need to authenticate with Touch ID as well)
- run mame (whatever game name) (literally type "run mame pacman" or whatever and wait for the crash)
- bt ...then paste the output.
I'll try this.
I'm not home until tomorrow night, but in the meantime I've tried with a xbox controller, and that worked. At home I have some neogeo look-a-like chinese controllers, that's probably causing the issue, but they seem to work fine with my older macbookpro running .254

just a note: running mame (with the ui) loads the joysticks, while running mame game doesn't.
The first stack trace looks a lot like memory corruption. The actual bug likely did the damage long before the point where it crashed. The second one I have no idea what would cause it to crash there (could be memory corruption as well).
There is an issue on arm with char defaulting to unsigned on android and the pi (not sure on macos ). It causes issues in many places such as brapboys not booting and random places and certain inputs not working working in some games.
Try adding ARCHOPTS="-fsigned-char" to the compile command line and see if that helps. Im not saying this is the issue on the mac but its is on android and pi. I dont use mac but its worth a test. https://developer.arm.com/documentation/den0013/d/Porting/Miscellaneous-C-porting-issues/unsigned-char-and-signed-char?lang=en
Sorry for wasting you time with that, its certainly causes issues an a few things on android and the pi.
anyways: I've tried with logitech Precision joypads and also get seg faults.

Just to resume:
I've tried different versions of mame (.249, .258, .258) both from sdlmame website or by compiling them.
- Works fine without joypad
- Works fine with XBox joypad via bluetooth
- Crashes with my neogeo clones joysticks (usb)
- Crashes with my logitech precision joypads (usb)
Is anything else I can test? Can I print out the stuff I get from the joypads with PySDL2? Is possible to have make spit out a xcode project and debug with that? (i'm not too eager to use lldb :D )
