No need for an if here, free(NULL); is void already.
OK
When I build the glibc, I got the error as follow:
CPP='gcc-4.2 -E -x c-header'

I don't understand what the error means
The problem may not be directly in your code. You should run the test
by hand in gdb, something like:
LD_LIBRARY_PATH=/root/storage/glibc-2.7/build-tree/hurd-i386-libc 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
to get a backtrace.
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
