-  const uptr AlignedReservedAddressRangeSize =
-      RoundUpTo(sizeof(ReservedAddressRange), MinAlignment);
-  const uptr HeadersSize =
+  static const uptr AlignedReservedAddressRangeSize =
+      (sizeof(ReservedAddressRange) + MinAlignment - 1) & ~(MinAlignment - 1);
----------------
Maybe use constexpr?
