Runtime panic on go v1.25.x running the example app.

[JoeGruffins]

Hi. I am on an m4 mac os v15.5 and attempting to run the example program in your readme but am hitting a panic. It could be my set up but unsure. Any help would be appreciated. Here is the full panic:

panic

Same issue using intel mac on v26.0.

[JoeGruffins]

The panic seems related to golang v1.25.1 and v1.25.2 on arm64. go v1.24.8 and lower work fine. The cause may be above me but will close this if a future golang version fixes it.

[JoeGruffins]

@martonp and I have determined this is an issue with this repo and go 1.25.x

[arturmelanchyk]

when I specify -gcflags "all=-N" it runs though
