+Subject: [PATCH] Fix GCC 12 dangling-pointer warning
+
+We're storing a persistent pointer to an ephemeral local variable
+which technically is a dangling pointer and the compiler is correct.
+However, since we never indirect the pointer, this is a safe
+operation and we can suppress the warning.
+
+Also, some C run-times (like MUSL) aren't including <stdint.h>
+indirectly so we must include it explicitly or we won't have the
+type definition for uintptr_t.
+
+Fixes issue #867.
