Not quite right. The model numbers imply a symmetric range.
It is processor dependent on whether the most negative
value is -2147483648. Without see the source, it's difficult
to say what OP hit. If her/his code is equivalent to
program foo
integer i
read(*,*) i
print *, i
end program foo
update to 4.8. or trunk.
This is trunk.
% gfc4x -o foo foo.f90
% ./foo
-2147483648
-2147483648
This is 4.7.something_revision.
gfc47 -o foo foo.f90
troutmask:sgk[214] ./foo
-2147483648
At line 3 of file foo.f90 (unit = 5, file = 'stdin')
Fortran runtime error: Integer overflow while reading item 1
If OP tries a simple assignment he/she will hit an issue
with a unary minus operator.
