[Bug 1069897] Re: gdb crashes on startup if run as root via sudo and ~/.gdbinit exists
I agree with Dave's comments in #3.
However, taking a closer look at gdb/cli/cli-cmds.c, I think further
changes need to be made to remove all possibility of a crash. The
behaviour of source_script_with_search() looks rather unusual in the
para-phrased snippet below (my comments prefixed by '/* XXX: '):
#---
old_cleanups = make_cleanup (xfree, full_path);
make_cleanup_fclose (stream);
if (stream == NULL)
{
/* XXX: since a cleanup was added for 'stream' before checking it opened
correctly, this appears to *guarantee* a crash if it didn't */
}
if (from_tty == -1)
{
/* XXX: ? this is already been done above */
make_cleanup_fclose (stream);
}

[Bug 1069897] Re: gdb crashes on startup if run as root via sudo and ~/.gdbinit exists
This looks to me as a bug in a debian specific patch; see debian/patches/gdbinit-ownership.patch + warning (not using untrusted file \%s\, file); + fclose (stream); + do_cleanups (old_cleanups); + return; As far as I can tell from the weird cleanup system, the do_cleanups is fclose'ing stream as well, and that's why it fails. commenting out the fclose(stream) there makes it work for me, and the fd is closed according to /proc/*/fd ** Changed in: gdb (Ubuntu) Status: Confirmed = Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069897 Title: gdb crashes on startup if run as root via sudo and ~/.gdbinit exists To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdb/+bug/1069897/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
