--- Comment #7 from jvdelisle at gcc dot gnu dot org 2008-11-15 19:39 --- Fixed on trunk. I will open a new PR for enhancement of this to better utilize the internal unit array by doing fewer newlines for namelists. -- jvdelisle at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution||FIXED http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37294

--- Comment #4 from burnus at gcc dot gnu dot org 2008-11-13 15:55 --- Patch was: http://gcc.gnu.org/ml/fortran/2008-11/msg00080.html I'm not completely satisfied with the patch it will break code such as: character(50) :: line(2) namelist /stuff/ n, m n = 123 m = 456 write(line,nml=stuff) which worked before. The true solution would be to do the same as NAG f95 does (cf. comment 2), but the challenge is to do is such that there is no performance penalty for code which fits into one line / for scalars. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37294

--- Comment #2 from burnus at gcc dot gnu dot org 2008-08-31 09:11 --- 9.3 Internal files (2) A record of an internal file is a scalar character variable. (3) If the file is a scalar character variable, it consists of a single record whose length is the same as the length of the scalar character variable. If the file is a character array, it is treated as a sequence of character array elements. I'm not sure that one necessarily has always to write: 1)STUFF 2)N=123, 3)/ I think NAG f95 does it standard conform and sensible: With: character(30) :: line(3) 1) STUFF N = 123/ 2) 3) With: character(10) :: line(3) ! or 15 1) STUFF 2) N = 123/ 3) With: character(9) :: line(3) 1) STUFF 2) N = 123 3) / With: character(8) :: line(3) 1) STUFF 2) N = 3) 123/ gfortran (and g95) print: Fortran runtime error: End of record when the data does not fit into a single record/array element. (I don't know how to decide without to many CPU cycles when to start a new record.) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37294
