irix6.5 bootstrap of 3.4 cvs of 20040515 fails in stage2 with

/d2/billingd/src/gcc/gcc/libgcc2.c: In function `__negdi2':
/d2/billingd/src/gcc/gcc/libgcc2.c:72: internal compiler error: Segmentation fault
The reduced test case is
typedef int SItype __attribute__ ((mode (SI)));
typedef unsigned int USItype __attribute__ ((mode (SI)));
typedef int DItype __attribute__ ((mode (DI)));
struct DWstruct {SItype high, low;};
typedef union
{
struct DWstruct s;
DItype ll;
} DWunion;
DItype
__negdi2 (DItype u)
{
DWunion w;
DWunion uu;
uu.ll = u;
w.s.low = -uu.s.low;
w.s.high = -uu.s.high - ((USItype) w.s.low > 0);
return w.ll;
}
which fails with
/d5/billingd/obj/gcc/gcc/cc1 -fpreprocessed libgcc2.i -quiet -dumpbase libgcc2.c -auxbase-strip libgcc/./_negdi2.o -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -version -o libgcc2.s
