I tried running nix run github:nixos/nixpkgs?rev=fab09085df1b60d6a0870c8a89ce26d5a4a708c2#bun on x86_64-linux, but I wasn't able to reproduce the issue.

[usdogu]

weird,

@usdogu have you tried in qemu built using nixos-rebuild build-vm ? that way maybe something in your configuration vs something with hardware type/version

[usdogu]

Fixed with the vm. Closing this since it's an issue in my side

[AlexMouton]

fwiw I am getting this as well using nixos on an i5 using @kilianar example

Thanks A

@AlexMouton nixpkgs packages official binaries. try downloading from https://github.com/oven-sh/bun/releases/tag/bun-v0.5.7

unzip bun-linux-x64.zip

if that crashes for you, maybe report issue upstream

[AlexMouton]

thanks @kirillrdy

[AlexMouton]

0.5.7 working

[kirillrdy]

0.5.7 working

and can you reproduce the crash with 0.5.5 ?

[kirillrdy]

also 0.5.7 has landed in nixpkgs

nix run github:nixos/nixpkgs#bun -- --version
0.5.7

does that work ?

[AlexMouton]

ah wait.
at 0.5.7 bun-linux-64 crashes, bun-linux-64-baseline works. at 0.5.5...same

[AlexMouton]

anyway, not a nixpkgs thing then

[NobbZ]

Baseline is built on "Nehalim" support, the non-baseline requires Haswell.

And Haswell is from 4th gen of Intel Core-i$whatever IIRC.

So for any older you probably need baseline. I also think, that nixpkgs should actually use the baseline, as that is much closer on the "do not optimize for a certain microarchitecture" than using haswell.

Alternatively build from source, really using no further micro-architecture related optimisations.
