[PATCH] major bug in mmap of lexer

Hi, Today while testing phar with phpMyAdmin, I was getting a really weird error - one of the files was turning into a series of Z's, munging the entire display. Thinking it was a phar issue, I instead tracked it down to a major problem in an edge case of zend_stream_fixup(). For files that are about 4085 bytes long, the buffer containing them was being erealloc()ed without re-assigning the new value to the zend_file_handle, resulting in efreed() value filled with Z's if --enable-debug was in the configure line (whew). A simple order change of assignment solves this one. The attached patches against 5_3 and HEAD fixes this and saves the day for pharred phpMyAdmin. Greg
