The following valid (though questionable) code snippet triggers an ICE
since GCC 3.1:
=========================================
#include <stdarg.h>
void foo(int, ...)
{
va_list va;
int i;
i = va_arg(va, int&);
}
=========================================
bug.cc: In function 'void foo(int, ...)':
bug.cc:7: warning: cannot receive objects of non-POD type 'int&' through '...';
call will abort at runtime
bug.cc:7: internal compiler error: in build_modify_expr, at cp/typeck.c:5643
Please submit a full bug report, [etc.]
