If I were to add a call to tellg() prior to appending additional data to the stream, the put pointer is now at the correct location and the output file now has all ten characters written to it, and not five. If the pointers are independent, then this should not happen. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40732
