Compiling the testcase g++.dg/template/error10.C produces

The error location contains invalid token '>>' that should
be replaced with '> >'.

error10.C:12: error: '>>' should be '> >' within a nested template argument list
error10.C:13: error: spurious '>>', use '>' to terminate a template argument list
error10.C:57: error: a call to a constructor cannot appear in a constant-expression
error10.C:57: error: template argument 1 is invalid
error10.C:57: error: invalid type in declaration before ';' token
error10.C:69: error: missing '>' to terminate the template argument list
error10.C:69: error: template argument 1 is invalid
error10.C:69: error: missing '>' to terminate the template argument list
error10.C:69: error: template argument 1 is invalid
error10.C:69: error: missing '>' to terminate the template argument list
error10.C:69: error: template argument 1 is invalid
