Subject: [PATCH] Fix compilation for gcc 15 with musl libc

when building on Gentoo with the musl profile, gcc 15 reports the
following errors:

The root cause is that including <memory> pulls in bits/align.h, and GCC
15 has removed the implicit inclusion of <stdint.h> from bits/align.h.
As a result, int64_t is no longer defined unless <cstdint> is explicitly
included.

This patch adds the missing <cstdint> include to fix the build.
