今天帮同事安装配置php_imagick，结果装是装上了apache也能正常启动，但是程序一new Imagick()就会导致Apache崩溃。

在google之后从Stack Overflow找到问题原因：

I’ve had the same issue today. You have to install version of Image Magick no higher than 6.6.4.0 – next builds are made using VC10 which seems to be incompatible with Apache VC9 + PHP5.3.x VC9.

ImageImagick dll for windows 在6.6.4以后用的都是VC10编译，所以不兼容vc9编译的php，虽然apache能正常启动，但是new Imagick的时候会导致apache崩溃。

解决办法就是安装低版本的ImageImagick
