valgrind的使用请参考： 使用valgrind进行内存泄漏和非法内存操作检测
最近在使用valgrind进行内存泄漏检测是时，竟然报错，如下：
VEX temporary storage exhausted.
Pool = TEMP, start 0x3967c4e8 curr 0x39b387b8 end 0x39b41027 (size 5000000) vex: the `impossible' happened:
VEX temporary storage exhausted.
Increase N_{TEMPORARY,PERMANENT}_BYTES and recompile.
vex storage: T total 541066736 bytes allocated
vex storage: P total 640 bytes allocated valgrind: the 'impossible' happened:
LibVEX called failure_exit(). host stacktrace:

其实这是一个libVEX的错误，临时的解决办法就是，使用valgrind时，添加命令行参数
--vex-guest-max-insns=25
问题解决。
