Crash on armv7l architecture: panic: unaligned 64-bit atomic operation

[mdartmann]

Hi,

when trying to run wireproxy, both on the latest tag v1.0.5 and the latest git commit, on my Banana Pi M2 Ultra (which has an armv7l chip), the program crashes with the following output:

The build runs just fine. I am using go 1.20 from Armbian Lunar which is based on Ubuntu Lunar (23.04).

Is 32-bit ARM supported/has it been tested yet? Do you know if there is a way to make this run with this architecture?

Thank you!

I solved this by using command go get golang.zx2c4.com/wireguard to update wireguard dependency to the latest version.

closing this issue as I switched to something else for my proxying needs
