--- Comment #5 from Paul <kapinos at rz dot rwth-aachen.de> --- Just tried all versions of gfortran available up to 10.2.0: the very same 'internal compiler error' is still reported using the initial reproducer. May that be connected to the old Linux we're using (CentOS 7.8)? pk224850@linuxc2:~/bugreports/GCC/007-ICE_unavailbale_Idir[524]$ ./runme007.sh mkdir: cannot create directory ‘foo’: Permission denied ------------------------------------------------------------------------------ f951: Warning: Include directory ‘./foo/bar’: Permission denied f951: internal compiler error: in cpp_diagnostic_at, at libcpp/errors.c:41 0x14f3468 cpp_diagnostic_at ../../../SOURCES/gcc-10.2.0/libcpp/errors.c:41 0x14f3468 cpp_diagnostic_at ../../../SOURCES/gcc-10.2.0/libcpp/errors.c:34 0x14f3468 cpp_diagnostic ../../../SOURCES/gcc-10.2.0/libcpp/errors.c:75 0x14f34f9 cpp_error(cpp_reader*, cpp_diagnostic_level, char const*, ...) ../../../SOURCES/gcc-10.2.0/libcpp/errors.c:89 0x9d5326 remove_duplicates ../../../SOURCES/gcc-10.2.0/gcc/incpath.c:260 0x9d58c9 merge_include_chains ../../../SOURCES/gcc-10.2.0/gcc/incpath.c:371 0x9d58c9 register_include_chains(cpp_reader*, char const*, char const*, char const*, int, int, int) ../../../SOURCES/gcc-10.2.0/gcc/incpath.c:498 0x654169 gfc_cpp_register_include_paths() ../../../SOURCES/gcc-10.2.0/gcc/fortran/cpp.c:722 0x654169 gfc_cpp_post_options() ../../../SOURCES/gcc-10.2.0/gcc/fortran/cpp.c:494 0x6c8b50 gfc_post_options(char const**) ../../../SOURCES/gcc-10.2.0/gcc/fortran/options.c:488 0x63044a process_options ../../../SOURCES/gcc-10.2.0/gcc/toplev.c:1384 0x63044a do_compile ../../../SOURCES/gcc-10.2.0/gcc/toplev.c:2200 Please submit a full bug report, with preprocessed source if appropriate.
