APAR status

• Closed as program error.

Error description

• A test program linked with the icu-4.6.1 library fails to load
  in IBM Debugger for AIX, V7.1 with the following error on AIX
  6.1:
  
  "Unable to load program
  testcase/debugger/29472,035,724/dbg_test
  /foo.
  The load failed because the exec() function failed.
  "
  
  Running the test case by itself on AIX6.1, the program could be
  loaded.
  
  It only fails to load when running in IDEBUG on AIX6.1.  On
  AIX5.3, idebug 7.1 can also load it.
  
  $cat foo.cpp
  #include <unicode/unistr.h>
  
  int main()
  {
      UnicodeString us = UNICODE_STRING_SIMPLE( "FooBar" );
      return 0;
  }
  
  xlC -q64 -g -I ../contrib/icu-4.6.1/include -L
  ../contrib/icu-4.6.1/lib -licuuc -licui18n foo.cpp -o foo
  

Local fix

• export LIBPATH=<path to directory>/contrib/icu-4.6.1/lib
  
  Then run the debugger.
  

Problem summary

• PROBLEM DESCRIPTION: The debugger was adding ./usr/lib:/lib. to
  the LIBPATH when no LIBPATH was specified. In this particular
  case, a production version of one of the libraries needed by
  the application already existed in /usr/lib but was out of
  date. So it gets picked up instead of the one in the
  application library folder. This resulted in the exec of the
  debuggee failing due to it not finding the correct shard
  libraries in the archive.
  
  USERS AFFECTED: Any user who is working on a system where a
  production version of the one of the libraries needed by the
  application already existed in /usr/lib but was out of date.
  

Problem conclusion

• When LIBPATH is not set, leave it unset. Problem is resolved.
  Apply service.
  

Temporary fix
