New Revision: 7489

Modified:
   trunk/gs/src/stream.c
Log:
Fixes bug: closing a filter pipeline with more than one adjacent temporary
stream (such as a compression filter with a predictor whose target was a
procedure) failed to flush all intermediate buffers, causing failures in PS3
CET 23-12*.  NOTE: This code (stream.c:swritebuf) is extremely delicate.
Regression checking is essential!
