Description

Since log4cxx 0.10.0 is core dumping on exit, we are unable to use it for the application.
The detailed steps are pasted down. Please get back to me for more info.

The mailing list has this issue being discussed -
http://mail-archives.apache.org/mod_mbox/logging-log4cxx-user/200804.mbox/ajax/[e-mail]%3e

Steps Followed:
--------------------
1) Downloaded the log4cxx 0.10.0 version and compiled with apr, apr-util 1.2.12.
2) The following Sample code is compiled with the above library -

==========================================================
#include "log4cxx/logger.h"
#include "log4cxx/basicconfigurator.h"
#include "log4cxx/propertyconfigurator.h"
#include "log4cxx/helpers/exception.h"

using namespace log4cxx;
using namespace log4cxx::helpers;

static LoggerPtr logger = Logger::getLogger("MyApp");

int main(int argc, char **argv)
{
int result = EXIT_SUCCESS;
try

{ // Set up a simple configuration that logs on the console. BasicConfigurator::configure(); // LoggerPtr logger = Logger::getLogger("MyApp"); log4cxx::File cfgFile(AGT_LOG4CXX_CFG_FILE); log4cxx::PropertyConfigurator::configure(cfgFile); LOG4CXX_INFO(logger, "Entering application."); LOG4CXX_INFO(logger, "Exiting application."); }

catch(Exception&)

{ result = EXIT_FAILURE; }

return result;
}

==========================================================
3) execute the binary - the output is as follows.
./a.out
16:36:33,706 [0x1] INFO MyApp:27 - Entering application.
16:36:33,707 [0x1] INFO MyApp:28 - Exiting application.
Segmentation Fault (core dumped)

4) If we try with the logger declaration with in the main(Comment the global declaration and uncomment the local declaration) - then this application works fine. It doenst core dump.

5) the core file genereated shows as follows -
===============================================================

6) After that tried the following changes in the main/cpp/objectimpr.cpp file as mentioned in the email thread - http://mail-archives.apache.org/mod_mbox/logging-log4cxx-user/200805.mbox/ajax/[e-mail]%3e

the core dump looks like this

==================================================================

7) After that I commented the apr_atomic_xchg32() call from the src/main/cpp/objectptr.cpp and made it to execute the #else - still the application coredumps
