          Issue ID: 14323
           Summary: Bad code generation in dfmt
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Keywords: wrong-code
          Severity: normal
          Priority: P1
         Component: DMD
          Assignee: nobody puremagic.com
          Reporter: briancschott gmail.com

dfmt at commit 48bc7ba0c2c115d3ba3175b591da4b46db57cb95 exhibits a code
generation bug.

dfmt is located at https://github.com/Hackerpilot/dfmt

To reproduce, check out that specific commit and run "make test" with the line
containing "version = WTF_DMD;" commented out. The code also seems to be
sensitive to whether or not the "-O" flag is enabled.

I've inspected the ASM dumps of the program and haven't been able to figure out
exactly where things are going wrong. I'll work on reducing this to a smaller
test case.
