Post scriptum:
* For
read (*, '(i18)') i
the value -2147483648 is accepted
But only if one has compiled the main program with -fno-range-check.
Cf. libgfortran/io/read.c's read_decimal function.
* For
read (*, *) i
the value -2147483648 is always rejected, independent of that flag.
Cf. libgfortran/io/list_read.c's convert_integer function.
Expected:
* A list-directed read gives the same result as a read with an edit descriptor.
* The value is always accepted - even without -fno-range-check.
This flag is completely nontransparent (with regards to the run-time
library),
it only works if the main program is compiled with that flag, and not even
the documentation of the flag mentions that the run-time library is affected.
See: -fno-range-check at
http://gcc.gnu.org/onlinedocs/gfortran/Fortran-Dialect-Options.html
Admittedly, it is mentioned at
http://gcc.gnu.org/onlinedocs/gfortran/_005fgfortran_005fset_005foptions.html
