It doesn't look like anything known. Please, provide more info about
your build environment.

1/ arch? i386 and amd64 should work, powerpc (or any tier2) may not[*]
2/ exact version? 8.3 can be 8.3-RELEASE or /stable/8 a few months old
3/ actual compiler? cflags? environ? options? requires full build log
4/ firefox20 affected? too late to fix firefox19 issues less than a week
   before the next release

[*] a/ pointyhat logs for tier2 archs aren't accessible to confirm
    b/ requires specific hardware, not on redports
    c/ upstream considers non-x86 as tier3 except for android;
       this leads to bitrot, especially on big-endian archs
