Retroarch crashing after unplugging and plugging controller

[vitormmatos]

Retroarch v1.10.3
OS: MacOS BigSur (Intel)
Controller: Dualshock 4

---

While plugging the controller, it does not get recognized at first try.
When unplugging and plugging again, few times it actually works, most of the times it just crashes.

Not sure if this should be 2 separate issues, but here it is nevertheless.

Give us a stack trace

[vitormmatos]

RetroArch(45274,0x1099d6e00) malloc: *** error for object 0x7f7ffa17fa00: pointer being freed was not allocated
RetroArch(45274,0x1099d6e00) malloc: *** set a breakpoint in malloc_error_break to debug
zsh: abort ./RetroArch

Needs to be a much more thorough stacktrace, that is not enough to go on and can't really be debugged.

[vitormmatos]

There wasn't generated a log file.
The best that could be done was to run it in the terminal and replicate the issue, and that's what I did.

Any suggestions?

Compile and run/debug RetroArch from Xcode, then a stack trace should show up.

It was difficult to reproduce but I saw the same issue. Most of the crashes I saw were related to double frees. I've been using the changes for a while with no crashes even when trying to disconnect and reconnect the controller quickly. I updated my local repo and saw a new controller related crash that I sent a separate pull request for first.
