I'm not sure I understand what you are saying. My concern is that calls to filebuf::seekoff(0,ios::cur) should not invalidate the buffer just to return a correct answer to "where am I?". Whether this is an accident of history or not, I've seen this usage enshrined in code as a respected idiom. Does your text above specify this? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45628
