           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@digitalmars.com
        ReportedBy: sandford@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

I spoke too soon. More test cases

dmd.exe HelloWord.exe  obj\Release\hello.obj obj\Release\b.obj occationaly fails if the root directory is deep.

dmd.exe c:\dmd\Test.exe  obj\Release\hello.obj obj\Release\b.obj   dfl.lib Fails even if the root directory shallow. dfl.lib is located in C:\dmd\windows\lib.

dmd.exe c:\dmd\HelloWord.exe fails if the root directory is long and many obj/lib files are included

Try running dmd under windbg.exe and see where it fails.

I'm not well versed in non-symbolic debugging, but I've included the output from several runs, since the exit code was changing. Is there anything else I should try?

DMD 1 tests
Often terminates with status -1073741819, but with no unhandled exception. I've
also used the latest D1 on a P4 a few times and haven't seen any errors yet.
I couldn't get a simple test case to error in windbg, but I could get something
from the VS debugger if I ran dmd twice in very quick succession

Compile a debug build of DMD:

c:\dmd\src\dmd> make -fwin32.mak
c:\dmd\src\dmd> copy dmd.exe c:\dmd\windows\bin

Then run dmd under windbg.

Could this be the same as the random OPTLINK crash on multi-core machines? It sounds pretty similar. Check if it still fails in 1.046 and 2.031.

Actually, I tried the optlink patch when it came out, and that didn't seem to fix it. However, I haven't had a crash on valid code happen in 2.031, so it's probably fixed, for the most part. Since this has been a stochastic problem, I had been waiting to see if it just got less frequent or has disappeared, before making a comment. Since it appears to be fixed, thanks!

Note:
I did run into a few crashes on invalid code (stuff to do with the new integer
rules) when porting my personal branch of DFL (since the main trunk is a few
revs behind). But that's probably a different bug.

Can you reproduce this with 2.031?  Walter fixed a bug that might well be related in that release.
