Thanks @rgmz - I could reproduce with the wazero repo on a Mac using GOARCH=amd64 go run github.com/zricethezav/gitleaks/[email protected] git -v. Can confirm it only happens with go 1.24 amd64 and not earlier or arm64. WIll look into it.

I reported the initial issue for gitleaks and can confirm that it fails with go-1.24.0/amd64 but works fine with go-1.23.6/amd64 (haven't tested with arm64)

Facing same issue in TruffleHog

[corani]

Wazero fix has been released in wazero:v1.9.0, I've created #194 to update.

[anuraaga]

Thanks everyone for the patience - I have cut a new v1.9.0 with the fix.

Thanks for the quick turnaround @anuraaga, much appreciated! 🙇‍♂
