jemalloc 3.0 or later as part of libc in FreeBSD 10.0 or later is no
longer compatible with phkmalloc syntax: MALLOC_OPTIONS vs. MALLOC_CONF.
"(malloc)" prefix above indicates jemalloc, not phkmalloc. So, the error
comes from linking against old libc e.g., from FreeBSD 9.3.

If you can't rebuild the affected component against new libc try setting
both environment variables instead of using /etc/malloc.conf.

  $ export MALLOC_OPTIONS=A MALLOC_CONF=abort:true
  $ /path/to/app
