Bug ID: 59568
Summary: complex type operator>> does not set eofbit for input
streams.
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c++

g++ -v
(Actually, it is set, it's just cleared before the return to caller)
The problem as I understand it is that the call to __is.putback(__ch)
resets the eofbit to 0, (in C++11) after a valid eof has been detected.
The next extraction operation fails on attempting to get a char type
but the eofbit is not set to 1.
This precludes the ability to do error checking on input files.
A simple solution I think would be to test for the eofbit before
attempting the putback. ie:
else
{
if (! __is.eof()) {
__is.putback(__ch);
__is >> __re_x;
__x = __re_x;
}
}
return __is;
}
in file /usr/include/c++/4.8.1/complex (This only fixes int types)
