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]
