           Summary: linker hangs with some very long enums & debug info
           Product: D
           Version: 1.019
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: critical
          Priority: P2
         Component: DMD

When trying to compile and link the attached testcase, the linker hangs and
starts to continuously write zeroes to the output EXE.

The bug is consistent for me, but it's easy to "break". Changing the file name
or removing the underscores at the end of the enum name, or removing some enum
members makes the bug go away. 

I scrambled the testcase enum member names (it was a real-life example) as it's
fairly confidential data. Like I mentioned above, the identifier names don't
matter - only their length does. It looks like it's an Off-By-N bug in the
linker.

Marked as "critical" as this is hard to isolate, and filling the disk with huge
zero-filled files is a Bad Thing.

The command to compile/link (and reproduce) is:
dmd -g testcase.d
