           Summary: cross imports produce repeated calls to a call
                    destructor
           Product: D
           Version: unspecified
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: brauningbar gmail.com


Created an attachment (id=394)
 --> (http://d.puremagic.com/issues/attachment.cgi?id=394)
package recreating the bug

Having a crossed imports between thre files of a personal project causes the
destructor of a class to get called REPEATED times. Tried various compiler
switches but no fix. When i compile with -unittest dtor gets called even more
times (like 6 times or even 9!)

The attached contains the files stripped with the bug, and a simple makefile
The compiler version i've tried was 2.030, i've tried with 2.019 and the dtor
calls were less than the former

Cannot reproduce on Windows. Tried several compiler versions, including 2.030
and 2.050.
Compiled with noflags, and with -O, -unittest. Tried compiling obj files
seperately. Tried all 6 combinations of ordering on the command line.
In every case, there was only one destructor call.

Can someone reproduce this on Linux?

THIS IS A SESSION SHOWING THE BUG in linux. 
The 2.050 doesn't emit bug but 2.039. I hope this is util
