Testcase to reproduce the issue
When building drizzle on mips, g++ crash with an internal compiler error. The
problem is reproducible with versions 4.4, 4.5 and 4.6, but not with version
4.3 (I didn't test earlier versions). I have attached a reduced testcase.
$ g++ -c ./testcase-min.ii

D>::value_type drizzled::internal::gcc_traits<T, D>::fetch(const volatile
