Got the PHP to compile and build, now I am doing some simple tests.  On initial invocation to PHP, I get the following exception:

Message . . . . :   Pointer not set for location referenced.           
Cause . . . . . :   A pointer was used, either directly or as a basing pointer, that has not been set to an address.                        
                                                                       
The exception was in c file zend_alloc.c, routine _erealloc().  The problem code is the first  line:

ZEND_API void *_erealloc(void *ptr, size_t size, int allow_failure ZEND_FILE_LINE_DC ZEND_FILE_LINE_ORIG_DC)
{
      zend_mem_header *p = (zend_mem_header *) ((char *)ptr-sizeof(zend_mem_header)-PLATFORM_PADDING);
        zend_mem_header *orig = p;
    
	DECLARE_CACHE_VARS
	ALS_FETCH();

	if (!ptr) {
		return _emalloc(size ZEND_FILE_LINE_RELAY_CC ZEND_FILE_LINE_ORIG_RELAY_CC);
	}
  .
  .
  .
}

The first line is referencing the pointer without checking if it is NULL.  I moved the first 2 lines after the if-check and it cleared up the problem.
