I don't want to run all my programs under gdb all of the time. I want to attach to the misbehaving program as soon as it misbehaves.
Analyzing core dumps after the fact isn't as powerful: I can't call functions in the offending program. Trying to recreate the problem under gdb is often difficult and sometimes impossible: gdb tends to change the way malloc()ed memory is laid out, so that a crash because of uninitialized memory suddenly vanishes when debugging. :-(
That'd also enable me to debug setuid processes; just attach to them from a root shell.
