* [Bug fortran/14942] New: Incorrect results with implied-do loops and list directed I/O @ 2004-04-13 19:51 gcc-bugzilla at gcc dot gnu dot org 2004-04-13 20:08 ` [Bug fortran/14942] [gfortran] " pinskia at gcc dot gnu dot org ` (7 more replies) 0 siblings, 8 replies; 9+ messages in thread From: gcc-bugzilla at gcc dot gnu dot org @ 2004-04-13 19:51 UTC (permalink / raw) To: gcc-bugs The use of list directed I/O and implied-do loops gives incorrect results.
