IMHO, yes.  It may end up being a duplicate, but we won't know if it 
doesn't get filed and analyzed.

The underlying causes for this kind of problem can result in bootstrap 
failures and it's far easier to debug something small like that testcase 
rather than debugging any we got this kind of failure on GCC itself.
