[Bug c++/39742] New: ice in C++ overload resolution

["dcb314 at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I just tried to compile the following code

void f( int, ...);

struct S
{
};

void
g()
{
        void f( int, ...);

        S t;

        f( 1, t);
}

void
f( int i, ...)
{
}

with GNU C compiler version 4.5 snapshot 20090409
and the compiler said

jul17c.cc: In function 'void g()':
jul17c.cc:15: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

This C++ source code used to work with the 20090402 snapshot.

Here is valgrind helping out with a stack backtrace
