gcc 4.4下如果在编译swoole的时候（即make阶段），出现gcc warning： dereferencing pointer ‘v.327’ does break strict-aliasing rules、 dereferencing type-punned pointer will break strict-aliasing rules 请手动编辑Makefile，将CFLAGS = -Wall -pthread -g -O2替换为CFLAGS = -Wall -pthread -g -O2 -fno-strict-aliasing，然后重新编译make clean;make;make install
