+Subject: [PATCH 056/104] fix: set min value when allocating alligned memory
+ buffers
+
+The function "posix_memalign()" requires that the alignment be at least
+sizeof(void*). In some situations the alignmask for some crypto algorithms
+is smaller then the minimum required. For ex. on 64-bit platforms where
+the alignment may be 4 bytes.
