I know, but I thought that either the subnormals should have been
treated in software by the libc, or the ldexp function

Package: libc6.1
Version: 2.3.1-16
Severity: normal
Consider the following program:
#include stdio.h
#include math.h
int main (void)
{
double x = ldexp (1.0, -1038);
fprintf (stderr, %g\n, x);
fprintf (stderr, %g\n, x + 1.0);
return 0;
}
When compiled and run, I get:

If they are not completely supported, the libc shouldn't generate
them (to avoid FPE signals when results of libc functions are used
in input of other operations).
