[jira] Created: (STDCXX-233) std::strstreambuf::seekpos() fails to
properly position get sequence
std::strstreambuf::seekpos() fails to properly position get sequence
--------------------------------------------------------------------
Key: STDCXX-233
URL: http://issues.apache.org/jira/browse/STDCXX-233
Project: C++ Standard Library
Type: Bug
Components: 27. Input/Output
Reporter: Martin Sebor
Moved from the Rogue Wave bug tracking database:
****Created By: sebor @ Jul 01, 2000 08:28:15 PM****
This program fails with exit status of 1. It exits successfully (with 0) when std::strstreambuf is replaced with std::stringbuf. I don't see anything in D.7.1 that would require this behavior. Looks like a bug...
The (enhanced) regress/test_bug10430.cpp exercises this bug and fails as a result.
#include <strstream>
int main ()
{
std::strstreambuf sb;
sb.sputn ("a", 1);
sb.pubseekpos (0);
char buf[2] = { 'X', 'Y' };
return !( 1 == sb.sgetn (buf, sizeof buf)
&& 'a' == buf [0] && 'Y' == buf [1]);
}

[jira] Closed: (STDCXX-233) std::strstreambuf::seekpos() fails to
properly position get sequence
Posted by "Martin Sebor (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/STDCXX-233?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Martin Sebor closed STDCXX-233.
-------------------------------
Resolution: Fixed
The test case passes with the latest trunk. The test mentioned in the issue has moved to a test named 27_setbuf.cpp (not in svn yet) and that one passes as well, so the problem must have been fixed a long time ago. Closing.

> This program fails with exit status of 1. It exits successfully (with 0) when std::strstreambuf is replaced with std::stringbuf. I don't see anything in D.7.1 that would require this behavior. Looks like a bug...
> The (enhanced) regress/test_bug10430.cpp exercises this bug and fails as a result.
