abort() called from nwind_on_exception_through_trampoline on AArch64

If you can grab the logs it should tell you which one was triggered.

Anyhow, hmm.... if I had to guess then most likely it has triggered the second abort (the first one is very unlikely and something would have to go extremely wrong for it to trigger).

Now that I think about it that check actually might not be correct and doesn't really make sense since when the control is given to the landing pad the value of the stack pointer will be higher than the address of the slot where the return address was stored, so we're basically checking whenever we've clobbered the stack ourselves. I'll remove it and hopefully you won't see this crash anymore.

I've pushed the fix on master; can you check if it works fine now?

[stoperro]

Thanks, we will check and update :)

Almost tested, had hard time compiling from scratch. The key for me was to use rustup target add mips64-unknown-linux-gnuabi64 to install toolset (yes, different arch), previously tried some other commands in rust and failed... maybe this is obvious for rust developers though.

Also, readme.md mentions "Install at least Rust 1.31", so I literally used 1.31.0 afraid of what newer versions may bring, which fails on:

error[E0658]: `Self` struct constructors are unstable (see issue #51994)

Seems to work on current stable branch though.

[koute]

Yeah, I need to update (or probably just remove it outright) the version mentioned in the readme and probably improve the cross-compiling instructions.

In general you should always use the newest available stable version.

@stoperro By the way, didn't I leave you with a script to compile all of this automatically? You might want to look around for it. (:

[stoperro]

Funny thing, I learned about that script 1 hour ago :) Certainly that would have been better approach.
Still, already compiled manually on my PC with our SDK, and likely said script is also proper.

[stoperro]

Took a while... but we finally were able to test it and the crash we had doesn't occur anymore after the fix 👍
