The error is reproducible but does not alwaya occur with same file when
performing a normal build.
I have attached test case for a file that always fails.
If I create pre-processed source with g++ -E I am able to compile this without
error.
I have bisected gcc and the error occurs with the introduction of the following
commit:-

A shell script is attached which will cd to the appropriate directory and build
the file which creates the error this should reside in the directory above the
untarred archive.
