Application server does not start if CTG is installed or
modifying LIBRARY variable. Local fixProblem 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

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. Temporary fix
