           Summary: GDB segfaults when running strace
           Product: gdb
           Version: 7.2
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
        AssignedTo: unassigned@sourceware.org
        ReportedBy: calimeroteknik@free.fr


The problem is simple : whatever the way, gdb segfaults when running strace in
it.

Here are examples of gdb debugging itself when producing the bug :
http://pastebin.archlinux.fr/427135 : very simple cases
http://pastebin.archlinux.fr/427133 : gdb debugging gdb with backtrace

Real debuggings failing (in gdb so we can have a backtrace, it's the same) :
http://pastebin.archlinux.fr/427127 (a program with debug symbols)
http://pastebin.archlinux.fr/427130 (just bash)

I use Arch Linux with GCC 4.5.1

Does this occur when you use the strace command with arguments? gdb crashes on
my system when I run strace with no arguments, but gdb's strace command seems
to work correctly otherwise.

Since you said the strace command always produces a segfault, I figured my bug
was different from this one, and I reported it at:

https://bugs.launchpad.net/ubuntu/+source/gdb/+bug/691814

(I haven't reported it here yet.)

But then I examined your examples in detail and saw that you're running strace
with no arguments. If strace works for you when invoked with arguments, then my
bug is probably a reproduction of yours.

Excellent. I have annotated my Launchpad bug report to indicate that it is a
duplicate of this.
