LO64499: SEGMENTATION FAULT AFTER DISPOSING OF DYNAMICALLY LINKING LIBNOT ES.SO IN RED HAT LINUX

APAR status

• Closed as program error.

Error description

• Using files in test_so.zip
  Log on as the user who installed Domino.
  
  Unzip the files in an empty directory in the user's home.
  
  cd to that directory
  
  Build test_notes and test_so with the command:
  
    make -f linux.mak
  
  USE THE MAKEFILE TO BE SURE YOU DO NOT STATICALLY LINK
  libnotes.so!
  Copy test_notes and test_so to the Domino executables directory.
   You
  may need root access.  The directory is typically:
  
    /opt/ibm/lotus/notes/latest/linux
  
  This directory should be in the path, and also in
  LD_LIBRARY_PATH
  Start the Domino server if it is not already running.
  
  Run test_notes.  You will see:
  
    dlopen successful
  
  
  
    dlsym successful
  
  
  
    initlotus successful
  
  
  
    termlotus successful
  
  
  
    dlclose successful
  
  Segmentation fault
  
  The segmentation fault takes place during a call to getenv after
  the
  shared library is released with dlclose().
  
  Run test_so which does the same thing but with a different
  shared
  library (libcurses.so).  No Segmentation fault.
  
  If you statically link libnotes.so by including -llibnotes on
  the
  link command line, you will get no Segmentation fault from
  test_notes.
  

Local fix

• Statically link libnotes.so.
  

Problem summary
