User tcalmant has commented on the issue:
"<p>Indeed, this exception is therefore caused by the lack of server, due to issue #29477[0A]https://ironpython.codeplex.com/workitem/29477</p>"-----------------
6. [New issue] formatting inconsistency between % and format
http://ironpython.codeplex.com/workitem/35580
User paweljasinski has proposed the issue:

'9.3126672485384569e+23'
Given the sys.float_info.dig returning 15, both values are correct, but what bothers me, is that they are different."-----------------
7. [New issue] % formattin for '%f#...' and '%g#...' are broken
