This internal compiler error is being generated when I add the
keyword 'typename' to a line of code that
before that was giving me an error that: SAX/wrappers/saxlibxml2.h:310: error:
expected primary-expression
before '*' token.
In the saxlibxml2.ii file, it is at line 35577.
Specs from /usr/local/lib/gc/mips-sgi-irix6.5/3.4.4/specs
Configured with ./configure
Thread model: single
gcc v3.4.4
Command line:
g++ -c -I../../Include/SAX ../../Include/SAX/wrappers/saxlibxml2.cpp -
o ../../Include/SAX/wrappers/saxlibxml2.o

Created an attachment (id=9143)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=9143&action=view)
The ii file from the compiler output where I received the seg fault.
Line 35577 in this file contains the 'typename' that I added to make this
compiler have an internal error. Without this keyword, I get a compile error.
So, it seems to be required...but I can't build my source.

Confirmed, here is a reduced testcase:
template<class a>
struct cla
{
template<typename b>
struct clb {};
};
namespace nasa { template<class a> struct clc {}; }
template<class a>
void doGetProperty(void)
{
cla<a>::clb<typename nasa::clc<a> *> *prop;
}

Your line should read:
typename SAX::basic_XMLReader<stringT>::template
Property<SAX::basic_DeclHandler<stringT> *>* prop;
If one fixes all four occurances in your file, the code compiles fine.
With your version
SAX::basic_XMLReader<stringT>::Property<typename
SAX::basic_DeclHandler<stringT> *>* prop;
"SAX::basic_XMLReader<stringT>::Property" is not a type, and therefore "<"
is the operator "less_than" which is followed by a type (followed by some
more stuff, but the compiler already crashed).
An even shorter testcase is the following:
===========================================
namespace N { template<int> struct A {}; }
template<typename> void foo()
{
+typename N::A<0>;
}
===========================================

Only the following:
if (TREE_CODE_CLASS (TREE_CODE (scope)) != tcc_type)
Should be:
if (!TYPE_P (scope))

I don't think that this is a proper fix, since the following IMHO valid
code snippet is rejected:
====================================================================
namespace N { template<int> struct A { operator int() const; }; }
template<typename> void foo()
{
+typename N::A<0>();
}
====================================================================

So this is an ice-on-valid and an ice-on-invalid bug then?

The testcase in comment #3 shows an ice-on-invalid. The testcase in
comment #7 is valid, and ices anyway.
