            Bug ID: 64522
           Summary: [4.8/4.9/5 Regression] Free-form source code:
                    -Wline-truncation is no longer enabled by default
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Keywords: diagnostic
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org

Using GCC 4.4, a free-form source code which exceeds the 132 character limit
showed by default the message:
  "Warning: Line truncated at (1)"

Using GCC 4.8, 4.9 and 5, this message is only shown with -Wline-truncation
(which is implied by -Wall).

As other compilers by default use -ffree-line-length-none (unlimited line
length), it makes sense to show this warning by default - or even to error out.
Currently, it may lead to difficult-to-find bugs.


[GCC 4.4 did not show this warning by default for fixed-form source code, which
makes sense]
