I've seen this on Linux too, on the status line the A: number grows very
rapidly, A-V too and ct increases but slower than the other numbers.
When I seek, the audio restarts as in the bug description.  MEncoder's
output on the console is completely normal. This happens with or without
ODML, and whether you convert the whole file, just parts of it with
-endpos or cancels it in the middle.

My encoding line for this test was:

mencoder $INPUT -ovc lavc -oac lavc -o tmp.avi -endpos 30

The input is MKV(H.264+AAC).

My m{player,encoder} version is dev-SVN-r27056-4.2.3, built yesterday.
