Issue #13744 has been reported by satoryu (Tatsuya Sato).

Bug #13744: Spawn doesn't work with options of symbol keys generated dynamically
https://bugs.ruby-lang.org/issues/13744

* Author: satoryu (Tatsuya Sato)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.5.0dev (2017-07-13 trunk 59321) [x86_64-darwin16]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
spawn works when giving options whose key is symbol literal: 

~~~
$ ruby -e 'spawn("ls", :rlimit_cpu => 100)'
~~~

But spawn fails when generating symbol from a String: 

~~~
$ ruby -e 'spawn("ls", "rlimit_cpu".to_sym => 100)'
-e:1:in `spawn': wrong exec option symbol: rlimit_cpu (ArgumentError)
        from -e:1:in `<main>'
~~~
