This compiles for me without error. When it runs, I get a stack overflow. The reason looks clear - foo(Args) is recursively calling itself. I don't think it's a bug in dmd.

Mac OS X 10.6.8 causes segmentation fault, but Scientific Linux release 6.0 64bit works fine. Does D allow above code? -------------- next part -------------- An HTML attachment was scrubbed...
