I tried the program and I confirm the incorrect result under
hppa-linux. The same code under hpux generates the correct
result. The problem might be the wrong rounding mode is set
by glibc. I believe that there was a recent fix for this.
I see no indication that the code traps on a PA8700. I think
you would get a report in kern.log if the insn trapped due to
an unimplemented trap. You might have the floating point
exception enables on causing traps on your machine.
