The code compiles fine with gcc 3.3.4 using about 50 MB without
optimization and 100 MB with -O3.
After adding a missing typename the code also compiles with gcc 3.4.0,
using about 100 MB with -O3.
It crashes however with gcc 3.4.1, 3.4.2 and mainline -
consuming more than 1.5 GB even with -O0 before the crash.
Given the speed of the memory allocation this looks like
an infinite loop in the compiler.
It's a regression on the 3.4 branch.

Here's a reduced testcase:
=========================
struct A {};
struct B : A
{
B(int);
B(B&);
B(A);
};
void foo(B);
void bar()
{
foo(0);
}
=========================
The copy ctor B(B&) seems to be responsible for the trouble.
Replacing it by B(const B&) cures the problem.
Upon closer inspection, the code seems to be invalid, since we
really need a copy ctor of the form B(const B&). However, we did not
diagnose this before 3.4.1, and the code compiled without trouble.
Phils regression hunter states
: Search converges between 2004-06-28-3.4 (#11) and 2004-06-29-3.4 (#12).
Btw, adding the missing typename and fixing the copy ctor in the
original testcase with the following patch makes the code compile
with gcc 3.4.1 and later:

Nathan, I suspect your patch for PR 16174
http://gcc.gnu.org/ml/gcc-cvs/2004-06/msg01175.html
is responsible for the regression.
Could you please have a look?

Hey, guess what, the test case isn't invalid (or the std does not say what it
means).
struct B : A
{
B(int);
B(B&);
B(A);
};
In the call to foo, we have to copy the rvalue temp created by B::B(int) --
this copy & temp can and will be elided, but we must check that it is doable.
B::B(B&) can't do this, because it has a non-const reference arg, but, B(A) can
do it via A's implicit const-copy constructor.
EDG 3.4 rejects this code though, and one of our auto_ptr testcases now
compiles, due to such a 'sideways' copy path. I'm clarifying with EDG as
to what the intent of the std is.

Nathan, even if there is not an official committee position on the correct
semantic of this program, is there way to get a patch in to stop cc1plus from
segfaulting?

TC1 fixed this, and EDG were kind enough to point me at the paper describing
the problem. I am working on this
