Passing semicolon through multiple variables fails test run

[miklosbagi]

I noticed this during asserting for variable contents originating from the http executor for grafana metrics style data.
This is a service where data changes frequently, so instead of hitting it with the http executor all the time for fresh, I work with the initial data captured in a variable, and work my way off to assertions.

Simplified example YAML:

name: "Venom Variable Passing Fail Example"
testcases:
- name: Passing the Semicolon
  steps:
    - type: exec
      script: echo '";"'
      vars:
        semicolon:
          from: result.systemout

    - type: exec
      info: "semicolon: {{.semicolon}}"
      script: echo "{{.semicolon}}" |wc -c
      vars:
        new_semicolon:
          from: result.systemout

    - type: exec
      info: "new_semicolon: {{.new_semicolon}}"
      script: echo

Note that new_semicolon will be 0:

 	• Passing-the-Semicolon
 		• exec PASS
 		• exec PASS
 		• exec PASS
	  	  [info] semicolon: ";"
	  	  [info] new_semicolon: 0

I'd expect 4:

> echo '";"' |wc -c
       4

Looks like this is due to an error thrown in the background:

      <system-err><![CDATA[
/var/folders/xk/nbn1dvld2z1dblaaaaaaahhhh0w0000gn/T/venom-346123047: line 1: : command not found

]]></system-err>

Further observations:

• Escaping as "\";\"" doesn't seem to help.
• Turning it around as "';'" seems to work fine.
