i still haven't been able to do a buildworld without cc segfaulting. :(
if i repeat the cc operation that segfaulted during buildworld with cc under
/usr/bin everything works fine. the segfault only occurs during buildworld
with the bootstrapped version of cc under /usr/ob/usr/src/tmp/usr/bin/cc.
i've replaced my /bin /sbin /lib /libexec /usr/bin /usr/sbin /usr/lib
/usr/lib32 /usr/libdata /usr/libexec directories completely and recursively
with ones built 19th of March (so the strlen bug should be fixed in all those
files because they have been dynamically or statically linked gainst a good
libc)
i've compared the output of `ident /usr/bin/cc` and `ident
/usr/obj/usr/src/tmp/usr/bin/cc` and this is the result:
-/usr/bin/cc:
+/usr/obj/usr/src/tmp/usr/bin/cc:

i'm really clueless right now. i thought maybe this could be due to bad
memory, but in that case shouldn't segfaults appear randomly? because this one
is 100% reproducable. maybe a bad sector in my hdd? i don't know. :(
cheers.
