+Subject: zlib: fix pointer alignment
+
+The function AllocForBrotli prefixes the allocated memory with its
+size, and returns a pointer to the region after it. This pointer can
+however no longer be suitably aligned. Correct this by allocating
+the maximum of the the size of the size_t and the max alignment.
+
+On Arm 32bits the size_t is 4 bytes long, but the alignment is 8 for
+some NEON instructions. When Brotli is compiled with optimizations
+enabled newer GCC versions will use the NEON instructions and trigger
+a bus error killing node.
+
+see https://github.com/google/brotli/issues/1159
