Dears

I would like to send a bug which was explicit by compiling the code:

        BOOST_STATIC_ASSERT (
            typeid (::connection::SPLight).name()
            == typeid(::connection::LightsStructure::value_type).name()
        );

This line is wrong, but it causes that gcc is going out of compilation process
due to internal errors (see backtrace below).

Regards.

connection::operator<<(std::ostream&, const connection::LightsStructure&)’:

Can you please attach preprocessed source for a testcase triggering this?

Below is separated FULL example :-).

// test_case.cpp
#include <boost/static_assert.hpp>
#include <typeinfo>

struct MyType1{};
typedef Mytype1 MyType2;

int main ()
{
    BOOST_STATIC_ASSERT (
        typeid (Mytype1).name()
        == typeid(MyType2).name()
    );
}

$ g++ test_case.cpp 

causes internal error.

The macro is expanded to:

typedef ::boost::static_assert_test< sizeof(::boost::STATIC_ASSERTION_FAILURE<
(bool)( typeid (Mytype1).name() == typeid(MyType2).name() ) >)>
boost_static_assert_typedef_12;

Regards.

Can you attach the *.ii file that is generated if you compile this with
-save-temps added to the command line?

Thanks.

[Bug c++/33355] [4.1 regression] ICE with typeid in template parameter

[reichelt at gcc dot gnu dot org]

------- Comment #6 from reichelt at gcc dot gnu dot org  2007-12-26 20:05 -------
Confirmed. Here's a reduced testcase:

===================================
template<typename> struct A {};

int i = sizeof A<typeid>;
===================================

The bug appeared in GCC 3.4.1 and is already fixed in GCC 4.2.0.
