LOL.  I mean, this really made me laugh out loud.  I see I've gotten a 
(probably well-deserved) reputation around here for pushing compilers to 
the limit and finding every bug imaginable.  Yeah, std.parallelism is 
horribly broken with GDC on Windows.  I haven't tested on Linux yet.  As 
far as I can tell the brokenness is deterministic, so it's very unlikely 
to be latent concurrency bugs.  The funny thing is that most of the bugs 
I've filed against GDC have been culled from (of all things) a 
statistics library I wrote.  Same with most of the bugs I found in the 
DMD 64-bit port.  How a statistics library could possibly be so good for 
finding compiler bugs that the test suites miss, I'll never know.

This is the kind of thing I'm looking for.  The biggest reason I wanted 
this info is so I know what the known defects are and don't have to 
waste time reducing and filing bug reports for bugs where there are tons 
of probably related unit test failures already.

BTW, my statistics library now passes all its unit tests on 64-bit Linux 
as of last time I checked.  There's still one bug that only occurs on 
32, and it looks like a rather nightmarish cross-module bug in a 15,000 
line codebase.  I haven't gotten around to reducing/filing it yet.

Yeah, I believe it.
