+Subject: [PATCH] src/rf64.c: Fix varargs related bug
+
+C's <stargs.h> functionality isn't type checked so that passing an
+`sf_count_t` (64 bits) by mistake in place of a `unit32_t` can cause
+errors. This would be fine if it was an error on every architecture
+and platform, but its not. This particular problem only manifested
+on armhf and some other Arm architectures. It was not an issue on
+32 bit x86.
+
+I have now fixed variants of this same bug several times.
+
+Closes: https://github.com/erikd/libsndfile/issues/229
