Subject: bug: audio/oggenc crash
Date: Fri, 7 Sep 2018 19:27:55 -0700 [thread overview]
Message-ID: <CAH_zEu5_S3jc60Tghg-UO_ememOGaNiKH3GyN7dLX2WWNLyyYA@mail.gmail.com> (raw)
when oggenc is run, it appears to always eventually crash:
cpu% audio/oggenc < /dev/zero > /dev/null
cpu% echo $status
oggenc 4556069: abort
the abort occurs due to free() called on a corrupted malloc()'d buffer
inside of libvorbis.
this call to malloc was inserted as a replacement for alloca(), which
of course we don't have. perhaps this bug was always in this code, but
never noticed since it might just trash autos on the stack.
