+Subject: [PATCH] EncodeAlphaInternal: clear result->bw on error
+
+This avoids a double free should the function fail prior to
+VP8BitWriterInit() and a previous trial result's buffer carried over.
+Previously in ApplyFiltersAndEncode() trial.bw (with a previous
+iteration's buffer) would be freed, followed by best.bw pointing to the
+same buffer.
+
+Since:
+187d379d add a fallback to ALPHA_NO_COMPRESSION
+
+In addition, check the return value of VP8BitWriterInit() in this
+function.
+
+Bug: webp:603
