scheibelp f27f20e5b3 replace dash with underscore in os name/version (#7381) ... Fixes #7356 In some cases OperatingSystem (e.g. LinuxDistro) was getting instantiated with a version that contains dashes. This breaks because the concretizer later converts this value to a string and re-parses it, and the '-' character is used to separate architecture components. This adds a guard in the initializer to convert '-' to '_'.		2018-03-09 10:03:58 -08:00
