The problem is this backtrace:

I can confirm this on 3.3.3 but works right on the mainline (after normal tweaks to the source for
the libstdc++ headers).

This runs into an endless loop on my machine, eating up all memory.
How unpleasant...

------- Additional Comments From reichelt at gcc dot gnu dot org 2004-01-23 21:29 -------
The source seems to be buggy. Line 61037 should read
for ( accts.first(); accts.current(); accts.next() ) {
instead of
for ( accts.first(); accts.current(); accts.next ) {
With this fix the file compiles without problems.
But of course the compiler shouldn't go into an infinite loop
on the buggy code. Here's a reduced testcase:
========================================
struct A {};
struct B : A
{
int foo();
};
struct C
{
B b;
C() { for ( ;; b.foo ) ; }
};
========================================
GCC 2.95.x issues an error message:
PR13663.cc: In method `C::C()':
PR13663.cc:11: invalid use of member (did you forget the `&' ?)
GCC 3.3.x goes into an endless loop.
GCC 3.0-3.2.3 and GCC 3.4 and mainline accept the code.
IMHO GCC 2.95.x is right and the code should be rejected
(however, I'm not really sure about that).

Just saying "b.foo" is taking the address of a bound member function
IIRC (one of the many gcc extensions). We then don't do anything with
this; that's a valid thing to do in the third clause of the for(;;)
statement.
It's nonsensical anyway.

I tried to backport Mark's patch from GCC-3.4.x to GCC-3.3.4 but it breaks
libstdc++-v3 with:
In file included from
/home/gdr/build/3/i686-pc-linux-gnu/libstdc++-v3/include/memory:54,

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
I suspect the cause is that in GCC-3.4.x and higher we have better idea of
what names should evaluate to, so the fix used by Mark is probably sufficient
there. For GCC-3.3.x I think I would have to rethink the logic.
