I also get a segfault just running nix run github:a-h/templ. When I run nix develop github:a-h/templ, I get a dev shell but theres no templ in it's PATH. It seems like the templ flake itself has some issues.

It works OK for me. Can't really help without knowing what the logs say.

nix develop won't have templ in the path, it's a development shell containing all the things you need to develop templ, not to use it. Re-reading the docs at templ.guide, I can see that's the docs are a bit wrong there. The dev shell used to contain a Neovim config, but not any more, because it was downloading way too much stuff.

This is what I get:
$ nix run github:a-h/templ
munmap_chunk(): invalid pointer
fish: Job 1, 'nix run github:a-h/templ' terminated by signal SIGABRT (Abort)
Earlier I got:
$ nix run github:a-h/templ
copying '/nix/store/7mhipfj7kvxyfj9zwkyf78ha1yfl07hp-source' to the store
fish: Job 1, 'nix run github:a-h/templ' terminated by signal SIGSEGV (Address boundary error)
In Bash it looks like this:
$ nix run github:a-h/templ
free(): invalid size
Aborted (core dumped)
Same SIGSEGV error when I use it in my flake.

Architecture, version of Nix, operating system...?

Ah yeah, sorry.
x86_64, nix 2.21.0, Arch Linux.
I tried in a fresh archlinux container (so no modifications by me), installed nix from the official packages and ran it. Got the same segmentation fault.
podman run -it --rm docker.io/archlinux:latest bash -c "pacman -Syq --noconfirm nix && nix --version && nix --extra-experimental-features 'nix-command flakes' run github:a-h/templ"
But this (increased verbosity) worked at least once but is now also failing:
podman run -it --rm docker.io/archlinux:latest bash -c "pacman -Syq --noconfirm nix && nix --version && nix -vv --extra-experimental-features 'nix-command flakes' run github:a-h/templ"
Is there a race condition in the build process of templ?
The errors I'm getting are completely random. I'm not sure if templ is the problem or nix itself. Weirdly I'm only getting this when I try to use templ.

Just tried it on native NixOS and that worked. I'm too tired, I'll reboot my Arch system and continue testing tomorrow.

@XenGi are you happy for this to be closed? It seems you said it worked?

Just as an extra data point, it's working OK for me on x86-64 Ubuntu with Nix installed. My previous example was running the flake on aarch-64 Darwin (M1 Mac).

Closed, since no further information was provided, and we've been unable to reproduce the issue on Linux machines, and both ARM64 and x64 Macs.
