After applying Dimitry Andric's patches to contrib/jemalloc and replacing
/usr/bin/as with one built last Sunday, I was finally(!) able to rebuild
head as of 234536:
FreeBSD freebeast.catwhisker.org 10.0-CURRENT FreeBSD 10.0-CURRENT #797 234=
536M: Sat Apr 21 10:23:33 PDT 2012 root@freebeast.catwhisker.org:/usr/o=
bj/usr/src/sys/GENERIC i386
However, as I was copying a /usr/obj hierarchy via tar -- e.g.:
root@freebeast:/common/home/david # (cd /var/tmp && rm -fr obj && mkdir obj=
) && (cd /usr && tar cpf - obj) | (cd /var/tmp && tar xpf -)
it ran for a while, then:
<jemalloc>: jemalloc_arena.c:182: Failed assertion: "p[i] =3D=3D 0"
Abort (core dumped)=20
root@freebeast:/common/home/david # echo $?
134
root@freebeast:/common/home/david # ls -lTio *.core
ls: No match.
root@freebeast:/common/home/david #=20
So ... no core file, apparently.
freebeast(10.0-C)[2] find /usr/src/contrib/jemalloc -type f -name jemalloc_=
arena.c
freebeast(10.0-C)[3]=20
No file named "jemalloc_arena.c", either.
But contrib/jemalloc/src/arena.c contains a function,
arena_chunk_validate_zeroed():
175 static inline void
176 arena_chunk_validate_zeroed(arena_chunk_t *chunk, size_t run_ind)
177 {
178 size_t i;
179 UNUSED size_t *p =3D (size_t *)((uintptr_t)chunk + (run_ind=
<< LG_PAGE));
180
181 for (i =3D 0; i < PAGE / sizeof(size_t); i++)
182 assert(p[i] =3D=3D 0);
183 }
Thoughts?
Peace,
david
