+Subject: [PATCH] SSE2/64-bit: Fix trans. segfault w/ malformed JPEG
+
+Attempting to losslessly transform certain malformed JPEG images can
+cause the nbits table index in the Huffman encoder to exceed 32768, so
+we need to pad the SSE2 implementation of that table to 65536 entries as
+we do with the C implementation.
+
+Regression introduced by 087c29e07f7533ec82fd7eb1dafc84c29e7870ec
+
+Fixes #543
