今天发现mysql的一个问题，当跑update语句的时候，mysql 服务会自动断掉，无论用 phpmyadmin, navicat , mysql workbench 甚至用 mysql命令行效果一样。
我的环境是 ： windows server 2008 R2 + mysql5.7.18-win64。

06:36:18 UTC - mysqld got exception 0xc000001d ; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. Attempting to collect some information that could help diagnose the problem. As this is a crash and something is definitely wrong, the information collection process might fail. key_buffer_size=8388608 read_buffer_size=8192 max_used_connections=2 max_threads=151 thread_count=2 connection_count=2 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 49892 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.

中间经过多种尝试，最后经过 google google google 查到解决方法，安装 2008 sp1的补丁就可以了，微软官方下载：windows6.1-KB976932-X64.exe
