Greetings. I'm running into an issue with crunchgen. The following
simplified test case works perfectly on the latest 5.7-stable amd64
and 5.6-stable i386:
# cat kcopy.conf
srcdirs /usr/src/bin
progs echo
# crunchgen -Em Makefile kcopy.conf
# make clean && make objs && make
rm -f kcopy *.lo *.o *_stub.c
cd /usr/src/bin/echo && exec make -f Makefile echo.o
`echo.o' is up to date.
cc -O2 -pipe -fno-pie -c kcopy.c
cc -O2 -pipe -fno-pie -c echo_stub.c
ld -dc -r -nopie -o echo.lo echo_stub.o /usr/src/bin/echo/obj/echo.o
crunchgen -h -k _crunched_echo_stub echo.lo
cc -static -L. -nopie -o kcopy kcopy.o echo.lo -L/usr/lib
strip kcopy
# ./kcopy
Usage: kcopy <prog> <args> ..., where <prog> is one of:
echo kcopy
# ./kcopy echo
#
However, the same on 5.7-stable i386 segfaults:
# cat kcopy.conf
srcdirs /usr/src/bin
progs echo
# crunchgen -Em Makefile kcopy.conf
# make clean && make objs && make
rm -f kcopy *.lo *.o *_stub.c
cd /usr/src/bin/echo && exec make -f Makefile echo.o
`echo.o' is up to date.
cc -O2 -pipe -fno-pie -c kcopy.c
cc -O2 -pipe -fno-pie -c echo_stub.c
ld -dc -r -nopie -o echo.lo echo_stub.o /usr/src/bin/echo/obj/echo.o
crunchgen -h -k _crunched_echo_stub echo.lo
cc -static -L. -nopie -o kcopy kcopy.o echo.lo -L/usr/lib
strip kcopy
# ./kcopy
Usage: kcopy <prog> <args> ..., where <prog> is one of:
echo kcopy
# ./kcopy echo
Segmentation fault (core dumped)
#
I get similar results when swapping in ls, pax, and so on. However,
the make release process generates a working instbin binary as used by
bsd.rd, so it's working elsewhere and it's not clear if there's a user
step I'm missing.
Dmesg of the affected system is below, thanks.
