NetBSD shark 1.5.2 NetBSD 1.5.2 (SHARK) #12: Sat Aug 18 06:04:05 CEST 2001     he@hai.urc.uninett.no:/usr/src/sys/arch/arm32/compile/SHARK arm32
>Description:
The following error message occurs when the package x11/xphoon is built:

gcc -O2   -I. -I. -I./X11 -I./X11/bitmaps  -I/usr/X11R6/include   -DCSRG_BASED   -DFUNCPROTO=15 -DNARROWPROTO    -c xphoon.c
xphoon.c: In function `hack_bits':
xphoon.c:500: internal error--insn does not satisfy its constraints:
(insn:HI 234 231 711 (set (reg:SI 8 r8)
        (mult:SI (reg:SI 8 r8)
            (reg:SI 8 r8))) 41 {mulsi3} (insn_list 231 (nil))
    (nil))
/usr/src/gnu/usr.bin/egcs/common/../../../dist/gcc/toplev.c:1369: Internal compiler error in function fatal_insn
*** Error code 1

Stop.

>How-To-Repeat:
Cd to /usr/pkgsrc/x11/xphoon on a Shark (DNARD) running NetBSD 1.5.2.
>Fix:
Compiling xphoon.c with -O1 instead of -O2 avoids the problem.
