Bug #: 54033
Summary: gfortran: Passing file as include directory - add
diagnostic and ICE with -cpp
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Keywords: diagnostic, ice-on-invalid-code
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: bur...@gcc.gnu.org
Based on the report by Vladimír Fuka at
http://gcc.gnu.org/ml/fortran/2012-07/msg00089.html
Do:
touch file
gfortran -I file test.f90
Result:
Nothing.
Expected: As with gcc:
cc1: warning: foo: not a directory [enabled by default]
(That's in gcc/incpath.c's remove_duplicates - which is publical accessible via
register_include_chains -> merge_include_chains -> remove_duplicates)
If one uses the preprocessor (-cpp), one even gets an ICE:
Program received signal SIGABRT, Aborted.
