----------------
Hmm, this look strange, at least. Seems to me, in this case the size of the long double is 128 bit (copied from the host), but device reports that it does not support 128 bit double. Seems to me, it is a problem with the device configuration. Why does the host translate long double to 128 bit fp, while the device translates it to 64 bit FP?
