------- Comment #3 from jvdelisle at gcc dot gnu dot org 2007-12-10 02:16 ------- First, you are relying on non-portable behavior:
F95 Standard 9.4.1.5 Error branch - subpart (2)-> "The position of the file specified in the input/output statement becomes indeterminate" So gfortran does not try to change the file position after the read and the subsequent reads continue to read bad values and ad-infinitum. The loop is in your program. Second, as a Quality of Implementation issue, and under these conditions we can do whatever we want, I have a patch testing that moves the file to the next record position. :) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34411
