I am not fully sure the bug is actually in on the libc sid. It looks
like that nvcc redefines part of this header in a way that is not
compatible with the new version of the header.
I think I've found where this is happening.
In file /usr/include/common_functions.h installed by nvidia-cuda-dev,
line 73, is the following:
extern __host__ __device__ __device_builtin__ __cudart_builtin__
void* __cdecl memcpy(void*, const void*, size_t) __THROW;
Removing, or commenting out (as per the attached patch), this line fixes
the build of eztrace-contrib and theano.
Does this seem like a sane fix?
