           Summary: Incorrect code generated for 'const double'
    Classification: Mono
           Product: Mono: Compilers
           Version: 2.2.x
          Platform: 32bit
        OS/Version: openSUSE 11.1
            Status: NEW
          Severity: Normal

zipped Monodevelop test solution

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:

the declaration const double largeClip = 100.0; generates a constant with value
-100.0.  A similar declaration on the following line generates the correct

Reproducible: Always

Steps to Reproduce:
1.Extract the Monodevelop solution from the attached zip file.
2.Run the test - value of constants is printed out
Actual Results:  
should print prop:0.1, largeClip:100, smallClip:100

Expected Results:  
prints prop:0.1, largeClip:-100, smallClip:100

I could not reproduce the error if the example is reduced further - but it is
consistent for the files enclosed. The dissassembled code is attached (bin
directory) which just shows the incorrect constant being generated, just before
the correct one.  The Console.WriteLine statement is in the
Axis.WorldToPhysical method.  Error occurs for mcs and gmcs
