------- Comment #6 from don dot wakefield at gmail dot com 2010-09-10 14:06 ------- Re: comment 5 - what is needed is for filebuf::seekoff(0,ios::cur) to:
1) *not* invalidate the buffer 2) *not* move the file pointer since all that special case asks is "where am I in the 'logical' file?" This can be accomplished by having filebuf::seekoff() recognize an off_type of 0, and a seekdir of cur, and special-case the code to call _M_file.seekoff(0,cur) (not moving the file pointer, right?) and then adjusting the resulting pos_type to reflect the true, earlier position held by gptr(). Am I missing something? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45628
