I expect it will take at least a couple releases before the 64 bit compiler is reasonably solid. Few will actually try it until it is released. That's just the way of things.

One difficulty is the D test suite does not have a lot in it to test the optimizer/code generator. That's because the test suite consists of tests for things that failed in the past, and the optimizer/code generator was already solid from the C++ usage. The C++ compiler test suite does test the optimizer/code generator, but it isn't 64 bit.

Depends on your definition of real world.  A whole lot of the dmd test suite is 
distilled past problems from real world
code.  What is usually called regression tests.  The 3 test suites aren't 
small.  Through those, a huge number of issues
similar to yours have been found and fixed.  There's a little app in the dmd 
test suite that actually drives the
testing.  It's small, but it's real worldish.

That said, I don't have any production d code of any flavor.

So am I really the only one that's tested DMD64 on any real-world code besides 
Phobos and druntime so far?
