You are correct. There is a problem with the x86_64. I was trying on a 32bit system which does not fail. But, on my x86_64, I am witnessing the same behaviour you reported. So, now, let's see what the developers say. Thanks.
$ clang sqrt.cpp
jcabrera@elimelec /cygdrive/c/source/c++/test
$ ls
a.exe sqrt.cpp
jcabrera@elimelec /cygdrive/c/source/c++/test
$ ./a.exe
