weird problem calling a fuction

Users called me up saying their packages/procedures no longer work. Of
course, they've been working for years. I've whittled it down to a test case
Note I've logged in as the query user created the function and then called
it sucessfully from dual. When I reference the function which the query user
owns and I'm also logged in as then it fails.

          return replace(sInputString, '''', '^');
