Expected behaviour

pact-go consumer test should run successfully without error

Actual behaviour

The test fails with the following error

unexpected return pc for github.com/pact-foundation/pact-go/v2/internal/native.(*Interaction).GivenWithParameter called from 0xe18a8f```

Steps to reproduce

The code is pretty match same as the example test on github.
https://github.com/pact-foundation/pact-go/blob/master/examples/consumer_v4_test.go

1. save the following go code in a file named `consumer_v4_test.go

Additional information

• Reproduced on github actions:
  https://github.com/m15o/pact-go-on-golang1.22/actions/runs/8644350699
• The error occurs if you specify -race flag in go test command.
• In other test SIGSEGV occurs.
  It looks similar as this: https://github.com/pact-foundation/pact-go/actions/runs/8647678365
• This does not happen on darwin/arm64.

Thanks, it's hard to know if the issue is with Go or something else at this stage. Appreciate the repro.

[YOU54F]

There definitely seems to be an issue in linux builds reported over in golang, and is affecting our ci runs with all published version of golang 1.22.x (0,1,2)

I've not tested linux aarch64 yet.

Definitely appreciate the repro

I've been using

docker run --platform linux/amd64 --rm -it -v $PWD:/app golang:latest
cd /app
apt-get update
apt-get install -y openjdk-17-jdk
make test

which gives me the same error on the first test

Tested against linux/arm64 and its fine against there, had to make some updates to support downloading the correct variant of the csv plugin for linux aarch64

using branch https://github.com/pact-foundation/pact-go/tree/deps/go_1_22

[YOU54F]

The error occurs if you specify -race flag in go test command.

yep can also confirm this. thanks!

TL;DR

Linux x86_64 users

• Using GoLang 1.22.x ?
  • Resolution: disable -race
• Need to use -race?
  • Resolution: downgrade to 1.21.x

[mefellows]

Thanks Yousaf for putting together the above. It doesn't seem to be a problem on Mac either (the OS I use for development). I'd suggest we sit on this to see where Golang takes it, and leave this as a sign-post for others.

[YOU54F]

Also seeing the issue on macos x86_64 solely on 1.22 when testing in GHA

[m15o]

I've filed a golang issue on this problem
golang/go#67670

[mefellows]

Will be interesting to see if they come back with anything, perhaps something will jump out at the maintainers there.

I suspect they'll want a more minimal repro, as there is probably a lot of digging / effort required to reproduce with the existing repro you have provided (not your fault, but it could be any number of things in both pact-go and in the rust core, or rust libraries that export the C interface). Perhaps we could find the FFI function that's causing the problem, and create a basic C interface that does the same thing until we have a minimal FFI that reproduces the issue (if possible)?
