Looking closer at bitrate.c (the problem only occurs when using -b), I
noted one detail not related to this, but in vorbis_bitrate_init(), some
memory is allocated with calloc() and freed with _ogg_free(), e.g,
bm->queue_packets.

[Later...]

Since pretty much the only C runtime stuff I could find in bitrate.c
(after a quick glance) was memory allocations, I changed them all to
_ogg_calloc. Now it works with multithreaded runtime libraries as well.
Haven't bothered to locate exactly which allocations that needs
clearing, but I only changed three to calloc() (at line 129, 130 and
135, IIRC)...

Dunno if it qualifies as a "compiler" bug, but there does seem to be a
difference in behaviour in the two runtime libraries.
