The patch kit changes the output of this case:
1 //PR c++/27668
2
3 template<typename class T, T = T()> // { dg-error
"nested-name-specifier|two or more|valid type" }
4 struct A {};
5
6 template<int> void foo(A<int>); // { dg-error "cast|argument" "" { target
c++98_only } }
but only for c++98, from:
g++.dg/template/crash55.C:3:19: error: expected nested-name-specifier before
'class'
g++.dg/template/crash55.C:3:25: error: two or more data types in declaration
of 'parameter'
g++.dg/template/crash55.C:3:34: error: 'class T' is not a valid type for a
template non-type parameter
g++.dg/template/crash55.C:6:29: error: a cast to a type other than an
integral or enumeration type cannot appear in a constant-expression
g++.dg/template/crash55.C:6:29: error: template argument 2 is invalid
to:
g++.dg/template/crash55.C:3:19: error: expected nested-name-specifier before
'class'
g++.dg/template/crash55.C:3:25: error: two or more data types in declaration

integral or enumeration type cannot appear in a constant-expression
g++.dg/template/crash55.C:6:29: error: template argument 2 is invalid
i.e. the 4th error moves from line 6 to line 3
("a cast to a type other than an integral or enumeration type cannot appear in
a constant-expression")
This change is reasonable, so the patch updates the dg-error
directives accordingly.
gcc/testsuite/ChangeLog:
* g++.dg/template/crash55.C: Update dg-error directives.
