           Summary: Regular expression groups are not populated as
                    expected
    Classification: Mono
           Product: Mono: Class Libraries
           Version: 2.2.x
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: System
        AssignedTo: mono-bugs at lists.ximian.com

The following expression reports incorrect results (can be run in the C# repl
if you have imported the System.Text.RegularExpressions namespace):

new
Regex(@"^((?'minimum'\d+)\+|(?'maximum'\d+)|(?'minimum'\d+)-(?'maximum'\d+))$",
RegexOptions.ExplicitCapture |
RegexOptions.CultureInvariant).Match("48").Groups["minimum"].Value

The result of the call to Match should include two groups, "minimum" and
"maximum". The "minimum" group should fail, and the "maximum" group should
succeed with "48" being stored as the value.

However, for any input string consisting solely of digits, the first digit is
placed in the "minimum" group.

Reproducible: Always

Steps to Reproduce:
1. Open the C# repl
2. Invoke the statement "using System.Text.RegularExpressions;"
3. Invoke the expression listed in the details
Actual Results:  
The repl reports "4"

Expected Results:  
The repl should report ""
