Bug ID: 57638
Summary: warning container: 'integer_cst’ not supported by
dump_type#<type error>
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: chris at bubblescope dot net
The following code (notice the function takes a long long, the template takes
an int. This code is invalid)
template<int x>
struct S {};
template<long long i>
void g(S<i>);
void f()
{
S<1000> t;
g(t);
}
Produces the warning (in svn head and 4.7.0)
t.cc: In function ‘void f()’:
t.cc:11:8: error: no matching function for call to ‘g(S<1000>&)’
g(t);
^
t.cc:11:8: note: candidate is:
t.cc:6:6: note: template<long long int i> void g(S<i>)
void g(S<i>);
^
t.cc:6:6: note: template argument deduction/substitution failed:
t.cc:11:8: note: mismatched types ‘long long int’ and ‘#‘integer_cst’ not
supported by dump_type#<type error>’
g(t);
^
t.cc:11:8: note: ‘S<1000>’ is not derived from ‘S<i>’
