           Summary: "lld -flavor link" causes R6002 - floating point
                    support not loaded.

R6002 - floating point support not loaded.

Software compiled statically with clang++ (not clang-cl) and linked with
libcmt(d).lib and libcpmt(d).lib generate a Runtime error soon into execution.

If linked with Microsoft's link.exe, it works properly.  This is new as of a
few weeks ago, but I'm unclear at which point this issue started.

I'm trying to find a simple example to demonstrate this, but I can't debug it
to find it.  As soon as I hit Retry, which should break at the offending line
of code, the software exits instead.

Strangely, it is not immediate, but happens after our software has been running
for a couple of seconds.  I can verify that we have already done several
floating point operations.
