[jira] Created: (STDCXX-522) std::filebuf::overflow(EOF) writes EOF
to file in unbuffered mode
std::filebuf::overflow(EOF) writes EOF to file in unbuffered mode
-----------------------------------------------------------------
Key: STDCXX-522
URL: https://issues.apache.org/jira/browse/STDCXX-522
Project: C++ Standard Library
Issue Type: Bug
Components: 27. Input/Output
Affects Versions: 4.1.3, 4.1.4
Reporter: Martin Sebor
The program below should run successfully to completion but instead it aborts (both in 4.1.3 and on trunk):
$ cat t.cpp && make t && LD_LIBRARY_PATH=../lib ./t
#include <cassert>
#include <fstream>
#include <ios>
int main ()
{
struct: std::filebuf {
int_type overflow (int_type c) {
return std::filebuf::overflow (c);
}
} buf;
buf.open ("file", std::ios::out);
buf.pubsetbuf (0, 0);
buf.overflow (std::filebuf::traits_type::eof ());
buf.close ();
std::ifstream in ("file");
assert (std::istream::traits_type::eof () == in.get ());
}
