external/local_config_mlir/include/mlir/IR/Attributes.h:783:20: internal compiler error: in assign_temp, at function.c:968

I am trying to build Tensorflow 2.0 on Ubuntu 16.04LTS I get the error with gcc 4.8, gcc 5, gcc 9.2, etc.

Here are the version of bazel and gcc:

ai) ubuntu@ip-10-0-1-71:~/tensorflow$ bazel --version
bazel 0.27.1
(ai) ubuntu@ip-10-0-1-71:~/tensorflow$ gcc --version
gcc (Ubuntu 9.2.1-17ubuntu1~16.04) 9.2.1 20191102

Here's the error message from gcc from bazel:

I created an issue on github Tensoflow, but they haven't responded ...
