Pretty much ever since the testcase gcc.dg/overflow-1.c was added to the 3.3.x 
branch testsuite, I've been seeing it fail on mips-sgi-irix6.5 with -mabi=64.  
Here's the first time I can find it:
http://gcc.gnu.org/ml/gcc-testresults/2003-12/msg00566.html
and it still occurs currently:
http://gcc.gnu.org/ml/gcc-testresults/2004-03/msg01481.html

I get:
overflow-1.c: In function `foo':
overflow-1.c:25: internal compiler error: in expand_simple_unop, at 
optabs.c:2328


To repeat the failure, target mips-sgi-irix6.5 and compile the following .i 
file with -O2 -S -mabi=64.  (You can use a cross-compiler.)

# 1 "overflow-1.c"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "overflow-1.c"
# 11 "overflow-1.c"
struct S {
  int key;
  int rnext,rprev;
};

void foo(struct S* H)
{
  int i, k;
  for (i=0; i<2; i++){
    struct S* cell=H+k;
    cell->key=i*(0xffffffffUL/2);
    cell->rnext=k+(1-i);
    cell->rprev=k+(1-i);
  }
}
