I cannot understand why Win64 phobos unittest fails in std.regex... Who can help me?

The error message which is showing by tester:

@braddr , half year ago you stopped some unittests in this commit. Is this error message related to the reason why you had disabled them?

OK, problem in win64 is fixed.

[braddr]

That commit was at the very early stage of win64 work and was later removed as Walter got things working. Chances are that there's still bugs in the win64 support as it's pretty young and not well battle hardened.

Thanks. Finally the problem was in my code, and MS linker was more strict than ld and optlink to the problem.
