I've found it to be true, and it looks like compatible with
"evaluation of an allocator" and elaboration (control, preelaborate?).
I don't know whether there is a sentence addressing this directly,
maybe the experts can tell?

Both ObjectAda and GNAT do this. I don't know whether it is at
all possible to intruct ObjectAda not to "preallocate" constant
string pointers.
