SIGABRT is ment to do exactly that. However, "ulimit" must allow for the
core to be created and core dumps won't work with multi-threaded
programs (I heared rumors that this was changed in 2.6.x).

Also, in cases of a freeze, attaching a debugger (gdb) might help as
much:

$ gdb /path/to/your/program `pidof program`
