Local fix Problem summary
****************************************************************
* USERS AFFECTED: All WebSphere Application Server users on    *
*                 AIX - possibly other platforms.              *
****************************************************************
* PROBLEM DESCRIPTION: App server errors when trying to start  *
*                      and system reports segmentation error.  *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
This is a problem for AIX users (and possibly others) who
tries to set one of the following environment variables
(via one of the client programs (admin console, wscp,
XMLConfig)to pass to an app server:

  PATH
  LIBPATH
  SHLIB_PATH
  LD_LIBRARY_PATH

Other environment variables are NOT affected.

This is due to the AIX compiler/linker mapping literal
literal strings to READ-ONLY memory segments in the
executable.  Symptoms will look something like the following
when user tries to start an app server:

SIGSEGV 11 (*) segmentation violation
        si_signo  11 : SIGSEGV: (*) segmentation violation

        si_errno  0 : Error 0

        si_code  51 : SEGV_ACCERR  addr: 0x100047F7

        stackpointer=3c08fdd8

        .

        ----------------------------
Problem conclusion
Changed code so that the string literal is copied to a local
buffer before processing the string.  Therefore, when markers
are stored, SIGSEGV is not produced.
