+Summary: GetHashCode() hack makes fields misaligned
+
+The GetHashCode hack that put the hash code at the beginning of the memory
+returned by malloc() causes misalignment of the fields: this makes
+platforms that require aligned access to doubles and int64 integers to segfault
+(malloc and GC_malloc return 8-byte aligned memory in that cases: the
+additional 4 bytes causes the misalignment). The hash code should either be
+stored at the end of the object or the hack should be removed.
