Symptoms:
	PHSS_18166:
	1. Older versions of pdf's cause CXperf to core dump
	2. 32 bit archived-linked pthreaded applications did not
	   collect thread data.  Possible application coredump
	3. Stripped executables could cause CXperf to divide by 0.
	4. Applications using shared libraries could easily
	   run out of memory
	5. The application could spin forever
	6. More loops than anticipated become invisible to CXperf
	   when +O3 used at compile time
	7. Calls to _setjmp would cause the application to core dump
	8. cxmerge incompatible with current pdf version

Defect Description:
	PHSS_18166:
	1. Incomplete implementation of PDF handling mechanism in
	   presence of old PDF versions
	2. pthread event handlers were not properly initialized
	3. CXperf assumes that the number of symbol table entries
	   is greater than zero - stripped executables will have
	   zero entries.
	4. CXperf runtimes assumes an average of 50 functions per
	   shared library.
	5. A lock in the CXperf runtime shutdown is never unlocked.
	   If the CXperf shutdown function is called more than
	   once, it could wait forever.
	6. Plethora of additional uninstrumentable loops produced
	   in programs compiled at +O3 exacerbated CXperf search
	   mechanism, causing missed loops.
	7. _setjmp calls do not follow calling convention, but
	   CXperf expected it to, and overwrote data
	8. build infrasructure problem + lack of MPI tests

	Resolution:
	1. Generate an error message when old PDF file is detected
	2. Initialized pthread event handlers correctly
	3. Removed these assumptions from CXperf, and made CXperf
	   issue a warning if it encountered stripped executables.
	4. Added a user flag -avg_shlib_funcs to CXperf,
	   by which the user can guide the CXperf runtime
	   on #shared libraries that it can encounter.
	5. Added unlocks, and code to handle multiple calls to
	   CXperf shutdown.
	6. Extend CXperf search mechanism with additional match
	   criterion to find more apparent missing loops.
	7. Rewrote CXperf setjmp handler in assembly to avoid
	   overwriting data
	8. fixed build problems
