+ * To avoid more recent compilers (specifically clang-14) from treating this

+ * cannot be declared as a function.  Moreover, the dst parameter cannot be
+ * cached in a local since this no longer references the union and again falls
+ * foul of the strict aliasing criteria.  Refer to #18225 for the initial
+ * diagnostics and llvm/llvm-project#55255 for the later discussions with the
+ * LLVM developers.  The problem boils down to if an array in the union is
+ * converted to a pointer or if it is used directly.

+ * This function was inlined regardless, so there is no space cost to be
+ * paid for making it a macro.
