Bug ID: 67623
Summary: interaction between cpp and Fortran
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: Joost.VandeVondele at mat dot ethz.ch
Target Milestone: ---
The C(++) preprocessor that is invoked on .F90 files can change Fortran
strings, leading to unexpected results. While it is OK to remove things that
are truly C comments (e.g. from headers included), this should not happen in
Fortran strings? At least gfortran and ifort show different behavior.
> cat test.F90
#define FOO
WRITE(6,*) "&
&/* foobar */&
"
END
> gfortran test.F90 ; ./a.out
> ifort test.F90 ; ./a.out
/* foobar */
>
