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
