Summary: I/O for reals: READ waits for input after "i" and "n"
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: [email protected]

Based on
https://www.jiscmail.ac.uk/cgi-bin/webadmin?A1=ind1102&L=COMP-FORTRAN-90#2
If one uses:
READ (*,*) real_variable
and enters "i"<enter> or "n"<enter>, gfortran does not immediately return with
an error but waits for further input. As it does not accept "N"<enter>"aN" but
only "NaN" and "Inf"/"Infinity" as input, this behaviour does not not make
sense.
For other characters, e.g. "e" or "d" it immediately returns with an error.
Expected: As NAG, ifort, pathf95 do (for the linked test case):
-9.9900000E+02
Input new value:
i
ioerr = 140 a = -9.9900000E+02
Result with gfortran (note extra input line):
-999.00000
Input new value:
i
ioerr = 5010 a = -999.00000
Input new value:
i
nf
ioerr = 5010 a = -999.00000
