Bug ID: 89724
Summary: Fortran diagnostics give wrong line number because of
math-vector-fortran.h header file
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: sje at gcc dot gnu.org
Target Milestone: ---
I am seeing some Fortran regressions in my testing, but only when I build and
test with the latest Glibc. The regressions are:
FAIL: gfortran.dg/continuation_6.f -O (test for warnings, line 261)
FAIL: gfortran.dg/continuation_9.f90 -O (test for warnings, line )
FAIL: gfortran.dg/continuation_9.f90 -O (test for warnings, line )
FAIL: gfortran.dg/continuation_9.f90 -O (test for warnings, line )
FAIL: gfortran.dg/continuation_9.f90 -O (test for excess errors)
FAIL: gfortran.dg/tab_continuation.f -O Nonconforming tab (test for errors,
line )
FAIL: gfortran.dg/tab_continuation.f -O Nonconforming tab (test for errors,
line )
FAIL: gfortran.dg/tab_continuation.f -O Nonconforming tab (test for errors,
line )
FAIL: gfortran.dg/tab_continuation.f -O Nonconforming tab (test for errors,
line )
When I run continuation_9.f90 by hand I get:
% install/usr/bin/gfortran -std=f95 -c continuation_9.f90
f951: Warning: ‘&’ not allowed by itself in line 23
f951: Warning: ‘&’ not allowed by itself in line 24
f951: Warning: ‘&’ not allowed by itself in line 25
Instead of
% install/usr/bin/gfortran -std=f95 -c continuation_9.f90
f951: Warning: ‘&’ not allowed by itself in line 3
f951: Warning: ‘&’ not allowed by itself in line 4
f951: Warning: ‘&’ not allowed by itself in line 5
The reason for the line number changes is that the Fortran program is reading
the file install/usr/include/finclude/math-vector-fortran.h and these lines are
getting counted as part of the line numbers. This file is coming from glibc
and was recently added. If I move it out of the way then I get the previous
results.
