Description Pétur Runólfsson 2003-02-24 09:26:00 UTC 
ostream::operator<<(int) doesn't change the streams error state if streambuf::overflow returns eof. This works correctly in gcc-3.2.1.

Release:
gcc version 3.4 20030222 (experimental)

Environment:
Red Hat Linux 8.0

How-To-Repeat:
See attachment.

Check _M_failed before writing and set it if the write failed.
