[ace-users] Issue after re-install of ACE 6.1.0 on Fedora 23

[Sunil Matta]

Odd problem of a simple program not exiting at end of main.


    ACE VERSION: 6.1.0

    HOST MACHINE and OPERATING SYSTEM:
        If on Windows based OS's, which version of WINSOCK do you
        use?:
Linux eoms1 4.5.6-200.fc23.x86_64 #1 SMP Wed Jun 1 21:28:20 UTC 2016 x86_64
x86_64 x86_64 GNU/Linux

    TARGET MACHINE and OPERATING SYSTEM, if different from HOST:
    COMPILER NAME AND VERSION (AND PATCHLEVEL):
g++ (GCC) 5.3.1 20160406 (Red Hat 5.3.1-6)

    THE $ACE_ROOT/ace/config.h FILE:
#include "ace/config-linux.h"

    THE $ACE_ROOT/include/makeinclude/platform_macros.GNU FILE:
include $(ACE_ROOT)/include/makeinclude/platform_linux.GNU

    CONTENTS OF $ACE_ROOT/bin/MakeProjectCreator/config/default.features
    (used by MPC when you generate your own makefiles):

    AREA/CLASS/EXAMPLE AFFECTED:
The following tests
Error: Bug_2610_Regression_Test  FAILED with exit status 1 after Time:1s
Error: Bug_2772_Regression_Test FAILED (time out after Time:316s)
ERROR: <Bug_3744_Regression_Test> failed: No such file or directory
Error: Bug_3744_Regression_Test  FAILED with exit status 255 after Time:1s
Error: Bug_3911_Regression_Test  FAILED with exit status 255 after Time:1s
Error: MT_SOCK_Test FAILED (time out after Time:315s)
Error: NonBlocking_Conn_Test FAILED (time out after Time:316s)
Error: Reactor_Fairness_Test  FAILED with exit status 1 after Time:92s


    DOES THE PROBLEM AFFECT:
        COMPILATION?
        LINKING?
            On Unix systems, did you run make realclean first?
        EXECUTION?
    Execution.
        OTHER (please specify)?


    SYNOPSIS:
Main fails to exit program.

    DESCRIPTION:
Had to upgrade my Fedora to 23 with a fresh install.
I had a simple Ace_Test example to enqueue a string and have svc()
dequeue the message block and string 10 times.
Some times the program exits at the end of the main. SOmetimes it
doesnt.

Quite often, the program doesnt stop and just hangs with the
following stack trace:
0x00007ffff763b9e8 in pthread_cond_destroy@@GLIBC_2.3.2 () from
/lib64/libpthread.so.0

    REPEAT BY:
int TestAceTask::svc() {
   std::cout <<  _PFUNC_ << ":" << std::endl;
   ACE_Message_Block* mb = 0;
   while (getq(mb) != -1)
   {
      if (mb->size() != 0)
      {
         const char* pc = (char *)mb->rd_ptr();
     std::cout << "str=" << pc << std::endl;
         mb->release();
      }
   }
   return -1;
}


    SAMPLE FIX/WORKAROUND:
