----------------------------------------
Bug #10859: Process.spawn raises TypeError when passing hash with symbols as env
https://bugs.ruby-lang.org/issues/10859

* Author: Jakub Jursa
* Status: Open
* Priority: Normal
* Assignee:
* ruby -v: ruby 2.3.0dev (2015-02-17 trunk 49623) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
### expected:
~~~
head :001 > Process.spawn({FOO: "bar"}, "bash")
=> 13479
~~~

### got in reality:
~~~
head :001 > Process.spawn({FOO: "bar"}, "bash")
TypeError: no implicit conversion of Symbol into String
...
~~~

when I pass {"FOO" => "bar"} as first parameter, everything works as expected. It would be nice though to have possibility to pass Hash with symbols as parameter (or, at least mention in documentation http://ruby-doc.org//core-2.2.0/Process.html#method-c-spawn that env hash cannot have symbols as keys)
