Testcase for the issue

The compilation of FParsec (available here https://bitbucket.org/fparsec/main/get/tip.zip ) fails with:

../FParsecCS/Text.cs(389,17): error CS0159: The label `Switch:' could not be found within the scope of the goto statement
../FParsecCS/Text.cs(434,21): error CS0159: The label `Switch:' could not be found within the scope of the goto statement

This seems to be caused by some interaction between "switch" and the scope of labels.
A simplified testcase (that builds fine on VS2012 and on Mono C# compiler version is attached.

Fixed in master
Comment 2 Andrea Canciani 2014-05-27 09:56:53 UTC
I confirm both that it fixes the testcase and that now FParsec can be built successfully with Mono.
Thanks! :)
