Hi all!

I am testing latest Eigen on an ODROID-C2 board (Aarch64) and I am getting the following error when compiling with Clang 3.5.0-10:

Code: Select all

I do not get this error with GCC, but I am trying Clang as Eigen's templates eats up all the RAM of the board (2 GB).
I read that Clang has slightly less memory usage so I'm hoping this gets fixed.

Edit:
This error does not happen in Eigen 3.2.7 & 3.2.10.

Edit2:
Does one have to email the developers to get an account on the bug tracker to do bug reports there?

Edit3:
In https://github.com/tensorflow/tensorflow/issues/3065 they have a workaround for this problem.
