Ok I see it.
In fbuf.c (fbuf_alloc):
/* Round up to nearest multiple of the current buffer length. */
newlen = ((u->fbuf->pos + len) / u->fbuf->len + 1) *u->fbuf->len;
u->fbuf->buf =

For the original test
program p
character :: z = 'z'
print *, repeat(z, huge(1_4))
end
I get

Dominique, what are you seeing? This is working fine with my system with -m32.

I have found that there is a practical limit of 2**28-1 on the size. The test
case:
program p
character, parameter :: z = 'z'
print *, repeat(z, (268435456)) ! 2**28
end
gives when compiled:
f951:

When using the REPEAT intrinsic as a parameter, the frontend is simplifying
this to an actual string constant of the requested length. In this process it
is attempting to allocate length + 1 in order to

I do agree, that some extra temporary data is necessary and there
should be a practical (high) limit for something like that.
