What steps will reproduce the bug?

Trying to build the Heroic Games Launcher (Git but should also reproduce with 2.17.2) with nodejs 24.4.1 will lead to the attached stack trace early on.

Downgrading to 24.3.0 solves the issue for me. To reproduce on CachyOS (or any Arch-derivative), use nodejs 24.4.1 (which the distro ships by default) and build from this PKGBUILD via makepkg -si: PKGBUILD

The build needs GCC to succeed, but also reproduces the issue with Clang-22git (which fails for different reasons later in the build process).

How often does it reproduce? Is there a required condition?

Always.

What is the expected behavior? Why is that the expected behavior?

A successful build.

What do you see instead?
