Issue 8505 remains a threads regression problem as far as I can see. Works fine with LDC2 and DMD 2.059, fails dismally with DMD 2.060.

I know this is asking a lot, but very few people understand threads well enough to investigate this. Would you be willing to?

By looking at the code I see it's almost the same as in issue 8774.
http://d.puremagic.com/issues/show_bug.cgi?id=8774
I think the root case is exactly the same - stack corruption with a nested closure.

So if you have some time I'd ask you to take a look at 8774 as there are no threads nor standard library involved in the latest reduced test-case that was derived from similar code.

Anyway I'm going to investigate 8505 too.

Thank you for doing the reduction. I looked at it, though, and it is terrifyingly complex :-)

Thank you.

Willing, yes; caveat actually being able to build DMD, Druntime and Phobos from Git clones. Able, not so sure, apart from 2012-12-30 and 2013-01-01 I seem to have very few free hours between now and end of February.

I'll see if I can get the Git clone / build bit working to lower the barrier to entry.

Thank you for giving it a go. For this issue, I don't think you need to build the compiler (just download the latest beta), but you will need to be able to build the library.

This project may be helpful:

  https://github.com/carlor/dlang-workspace

It has been announced here:

  http://forum.dlang.org/thread/ygwzndxbwzrxzlhuooty@forum.dlang.org

I had to do an additional step to get it working:

  $ chmod a+x posix/gen.sh

Sadly this does not work with symbolic links due to use of .. within a shell script that uses cd. The script needs rewriting to set up absolute paths at the outset and then work with them rather than relative paths.

I guess I should do the rewrite and submit a pull request. We'll see.

Only needed if you want to do:

$ posix/gen.sh

rather than

$ bash posix/gen.sh

It also needs to have a clean as well as a generate. Looks like a sever rewrite is coming up!

Also I think this needs to be made into a Git multi-module project so that the cloning and update pulling of the repositories is handled automatically by Git.

I have rewritten the script to handle symbolic links and cleaning but this still leaves a problem with one of the components which insists on an exact relative position of components as real directories. This means there are too many assumptions in the DMD/Druntime/Phobos build for it to be considered stable.

Whilst I think SCons can easily handle all this better than the Make scripts currently there, I have no intention of promoting that solution as I realize many want to promote a D-based build solution for C, C++, D systems.

Also of course, I am a n00b to the build of DMD/Druntime/Phobos and so have no right to have strong opinions :-)  What I can say is that the current system isn't really up to scratch for someone wading in to it from scratch.
