           Summary: Unhandled win32 exception on successful exe
                    compilation
           Product: D
           Version: 2.027
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: ice-on-valid-code
          Severity: regression
          Priority: P3
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: sandford at jhu.edu


DMD generates an unhandled win32 exception when successfully compiling an exe
from a set of object files. It has occurred over a wide variety of code and on
multiple systems (Core 2 duo, Corde 2 quad and AMD dual core) and OS (XP,
Vista) and has also occurred with the command shell's is limited to a single
processor. The error is stochastic, though is almost always generated and
occurs both on file creation and overwrite. It appears to not happen on first
use, but does happen on subsequent uses (i.e. it may occur only when the file
system is warmed up). Only occurs with relative exe pathnames, not with
absolute path names. 

Test cases derived from the Code::Blocks D program template

doesn't work
dmd.exe bin\Release\HelloWord.exe  obj\Release\hello.obj

seemed to work on 2.029, but not 2.030
dmd.exe bin\HelloWord.exe  obj\Release\hello.obj

works in 2.030
dmd.exe HelloWord.exe  obj\Release\hello.obj

works
dmd.exe c:\really\long\path\bin\HelloWord.exe  obj\Release\hello.obj
