Nah. All you have to do is something like the following: ulimit -c unlimited; useradd foo; gdb /usr/sbin/useradd core; bt full; or similar. You'll also want to install libc6-dbg gdb; and similar. This will give you an idea of where the code is segfaulting, and whether it's in a library which useradd is calling, or something else entirely. If the backtrace doesn't look at all useful, something like: apt-get build-dep passwd; DEB_BUILD_OPTS="nostrip,noopt" apt-get source -b passwd; should in theory give you a passwd .deb file with debugging symbols and no optimization which you can then install to give you a more useful backtrace. You also might start by just reinstalling passwd in case there was some corruption somewhere to make sure you can replicate the segfault. -- Don Armstrong http://www.donarmstrong.com I finally developed a computer with feelings.
