[Bug translator/6905] New: process("a").statement("main@/root/a.c:*") fails by giving error message.

["srinivasa at in dot ibm dot com" <sourceware-bugzilla at sourceware dot org>]

Environment: elfutils-0.137, systemtap-20080913 snapshot.

I was developing testcases for uprobes, But any attempt to probe all statements
of a file fails by giving error message.

Consider a .c file /root
=================================
 1 #include<stdlib.h>
  2 int main()
  3 {
  4 int i=0;
  5 i = i + 5;
  6 printf("i value is %d \n", i);
  7 return 0;
  8 }
================================

Execution of below script fails by throwing error message.
./stap -vvvvvv -e 'probe process("/root/a.out").statement("main@/root/ex.c:*") {
printf("%s\n",pp())}'
