I tried it. but I couldn't even start gdb. I got the same error when I 
ran gdb.

gdb: hurdmalloc.c:287: _hurd_free: Assertion `((h)->check) == 
0x8a3c743e' failed.
Aborted

If I run gdb with the default glibc in my system,

gdb --args /root/storage/glibc-2.7/build-tree/hurd-i386-libc/sunrpc/rpcgen -Y 
../scripts -c rpcsvc/bootparam_prot.x -o 
/root/storage/glibc-2.7/build-tree/hurd-i386-libc/sunrpc/xbootparam_prot.T


(gdb) run

I don't get anything useful.
