本人数据库小白，遇到解决不了的问题了 特地来论坛求教：
最近在公司的本地windows服务器搭建一个bugzilla的测试环境，连接的也是同一个机器搭建的mysql服务器，搭建的步骤走完之后，bugzilla成功启动，首页展示正常，但是当我登录的时候，bugzilla就报错链接不到mysql，我一查进程确实死了，但是我启动mysql之后，同样的操作mysql依旧直接进程down掉。bugzilla的页面报错如下：[color=#FF0000][color=#FF0000]DBD::mysql::db selectall_arrayref failed: Lost connection to MySQL server during query [for Statement "SELECT DISTINCT grantor_id, member_id
FROM group_group_map
WHERE grant_type = 0"] at Bugzilla/User.pm line 869.
Bugzilla::User::groups('Bugzilla::User=HASH(0x2cfc93c)') called at Bugzilla/User.pm line 1024
Bugzilla::User::in_group('Bugzilla::User=HASH(0x2cfc93c)', 'admin') called at E:\bugzila\bugzilla-5.0\index.cgi line 39报错里的这个sql我试了下直接在mysql执行，也是进程直接挂：
SQL 查询： SELECT DISTINCT grantor_id, member_id
FROM group_group_map
WHERE grant_type = 0 LIMIT 0, 25MySQL 返回：
#2006 - MySQL server has gone away这个mysql我之间用都是正常的，包括数据库 表结构的创建，和其他服务同步数据等，就是这个bugzilla服务一连就挂掉，实在想不出问题的原因了，希望各位指点迷津 谢谢了

01:17:27 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.Thread pointer: 0xe525a70
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
