--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> --- True, although it has been broken (though didn't crash) already around in r110000: MALLOC_PERTURB_=225 /usr/src/gcc-test/obj/gcc/cc1plus.110000 -include ./pr58893.h -include xxx.h pr58893.c -quiet -o /tmp/pr58893.s <command line>:3947580:58: error: xxx.h: No such file or directory (note the completely bogus line and column info). Perhaps open_file_failed should use cpp_error_with_line instead of cpp_errno, at least when invoked from within _cpp_find_file/_cpp_stack_include with type == IT_CMDLINE (or IT_DEFAULT?), because pfile->cur_token[0] as well as pfile->cur_token[-1] points to uninitialized memory at that point. Tom/Dodji, any thoughts on this?
