Can you post an example command to repro so I can look into it more closely? Thanks!

Not sure what you mean by repro but this is a simple command that would cause issues if you were to run it. Not issues with your tool, but BASH will background the command up to the ampersand and then set the variable other to 3

curl http://example.com/foo/123?stuff=1&other=3
