Synopsis: ICE in grokdeclarator, at cp/decl.c:10142
State-Changed-From-To: analyzed->closed
State-Changed-By: reichelt
State-Changed-When: Wed Jan 15 05:22:20 2003
State-Changed-Why:
Fixed in gcc 3.4-20030113 with the new parser.
For the first reduced testcase
---------------------------snip here---------------
struct A
{
template <typename T> struct B {};
};
template <typename T> struct C
{
typedef A::template B<void> Type;
};
---------------------------snip here---------------
which lacks a typename after the typedef, we now get the error message
PR8061.cc:13: error: type `A' is not derived from type `C<T>'
PR8061.cc:13: error: ISO C++ forbids declaration of `B' with no type
PR8061.cc:13: error: template-id `B<void>' used as a declarator
PR8061.cc:13: error: expected function-definition
For the original testcase we get (among other messages) the equivalent
message (c:/boost/boost/python/detail/def_helper.hpp:54 is the position
where the ICE occured before):
In file included from test.cpp:9:
c:/boost/boost/python/detail/def_helper.hpp:54: error: type `
boost::python::detail::tuple_extract_impl<boost::python::detail::tuple_extract_base_select<Tuple,
Predicate>::match>' is not derived from type `
boost::python::detail::tuple_extract_base_select<Tuple, Predicate>'
c:/boost/boost/python/detail/def_helper.hpp:54: error: template-id `
apply<Tuple, Predicate>' used as a declarator
c:/boost/boost/python/detail/def_helper.hpp:54: error: expected
function-definition
The second reduced testcase also also gives a correct error message without ICE.
(Testcases in preparation.)
