           Summary: D DLLs do not support exceptions
           Product: D
           Version: 1.023
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: daniel.keep+d.puremagic.com@gmail.com


If an exception crosses the boundary between a DLL and its host, it causes the program to crash out to a system dialog.  This effectively makes D-based DLLs useless, unless you wrap every single call in try/catch.  This throws a rather large stick in the spokes of getting Phobos into a DLL.

At a minimum, the web page on doing DLLs in D should be updated to explicitly state this limitation.

Will attach a complete test case presently.

Test case

Compile using build.cmd, then execute host.exe.  It should get as far as printing "Hello, from plugin2!" before crashing.  Commenting out "throw new Exception..." from plugin.d and recompiling causes the crash to disappear.
