[Bug c++/13578] New: Internal compiler error

[mahall at ncsa dot uiuc dot edu]

The test code causes g++3.3.1 to dump core. The code is invalid, and produces
a valid error when compiled under g++2.95

> g++295 testfault.C
testfault.C: In method `int CrashingClass<XX>::crash(int) const':
testfault.C:9: non-template type `key_compare' used as a template
testfault.C:9: parse error before `;'

> g++311 testfault.C
testfault.C: In member function `int CrashingClass<XX>::crash(int) const':
testfault.C:9: internal compiler error: Segmentation fault

: Search converges between 2003-07-19-3.3 (#169) and 2003-07-20-3.3 (#170).

Most likely caused by:
<http://gcc.gnu.org/ml/gcc-patches/2003-07/msg01996.html> since this patch went only in for 
3.3.1 and did not make its way to the mainline at all.

Here's an even shorter testcase that causes an ICE with checking enabled.

=======================================
template <typename> struct A
{
    typedef int X;
};

template <typename T> struct B : A<T>
{
    typename X<T> x;
};
=======================================

The error message is:

PR13578.cc:13: internal compiler error: tree check: expected record_type, have 
   integer_type in lookup_template_class, at cp/pt.c:4111


Andrew's guess about the patch that caused the regression is correct.
Mark, you are the author. Could you please have a look?
