This happens since ffmpeg r23402 on Linux too:

svn log -v -r23402 libavcodec/
------------------------------------------------------------------------
r23402 | stefano | 2010-06-01 10:07:07 +0200 (Tue, 01 Jun 2010) | 8 lines
Changed paths:
   M /trunk/libavcodec/avcodec.h
   M /trunk/libavcodec/eval.c
   M /trunk/libavcodec/eval.h
   M /trunk/libavcodec/opt.c
   M /trunk/libavcodec/ratecontrol.c

Make ff_parse_expr() and ff_parse_and_eval_expr() return an int
containing an error code.

Allow these functions to convey the reason of the failure to the
calling function, failure which is not always due to a parsing error
but it may depend for example on a memory problem.

Also fix several potential memleaks.
