OK, so pg_rewrite seems to be broken. Not good...

You need to do "gdb /path/to/postgres/executable core".
Or try it like this instead:
* fire up psql in one window
* determine PID of backend connected to psql
* attach to live backend process with gdb:
gdb /path/to/postgres/executable
attach PID
cont
* issue vacuum command to psql
gdb should catch the crash and then you can issue "bt".
