--- Comment #1 from John David Anglin <danglin at gcc dot gnu.org> ---
Starting to think this is a bug in the generic narrowing code:

hread 7.1 "test-narrowing-" hit Breakpoint 4, 0xf9224470 in __GI_fetestexcept
    (excepts=1) at ../sysdeps/hppa/fpu/ftestexcept.c:32

(gdb) p/x $ret0
$1 = 0x10
(gdb) p/x $r26
$2 = 0x1
(gdb) bt
