This is not target-specific:
$ cat u.f90
print *, real(huge(1.0_8),4)
end
$ gfortran u.f90
u.f90:1.16:
print *, real(huge(1.0_8),4)
1
Error: Arithmetic overflow converting REAL(8) to REAL(4) at (1). This check can
be disabled with the option -fno-range-check
f951: internal compiler error: Segmentation fault
