           Summary: Regex hogs memory
           Product: Mono: Class Libraries
           Version: unspecified
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: System

"^[^.\d]*(\d+)(?:\D+(\d+))?" should match "MD 9.18", but all it does is hog CPU
und memory resources endlessly (will probably crash on x86 due to address space
limitations. my x64 started swapping at 5gb for the mono process, kill -9
helped). Removing the complete first expression solves this, MONO_OLD_RX works
