assemble_alias in varasm.c sets varpool->alias to 1, but fails to set
varpool->extra_name to anything.

This leads to trouble further down the line. In my case, varpool_remove_node
fails with a NULL-pointer exception.

This appears to be target/host independent. So far, the only work around I have
is to disable optimization.

Test case to follow ...
