Bug 2978 – Unhandled win32 exception on successful exe compilation

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

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?

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.

(In reply to comment #6) > 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.

I believe this was fixed in dmd 1.046 and 2.031. Reopen if not.
