Gherkin C tests fail on Alpine Linux

[aslakhellesoy]

Summary

Approval tests (diffing golden masters) fail on Alpine Linux

Expected Behavior

I'd expect it to work just as on other Linuxes and OS X.

Current Behavior

The uri property of gherkin-document events is empty:

bin/gherkin --no-source --no-pickles testdata/good/background.feature | jq --sort-keys --compact-output "." > acceptance/testdata/good/background.feature.ast.ndjson
diff --unified <(jq "." testdata/good/background.feature.ast.ndjson) <(jq "." acceptance/testdata/good/background.feature.ast.ndjson)

Possible Solution

Steps to Reproduce (for bugs)

docker run -v $(pwd):/app -it cucumber/cucumber-build:1919bbc16bcd230522be530efc885b29 bash
cd gherkin/c
make .compared

Your Environment

• Version used: HEAD of master
• Operating System and version: Alpine Linux 3.5 running in Docker

Hi @brasmusson - any idea what might be causing this?

[brasmusson]

The uri originally comes from the command line arguments, which are passed as arrays of char (as defined by the signature of main). This differs from most other data (originating from the feature files) which is read into arrays of wide-char (wchar_t). This is the angle I would explore first
