BUG#13979418: SHOW BINLOG EVENTS MAY CRASH THE SERVER

Browse Source 
The function mysql_show_binlog_events has a local stack variable
'LOG_INFO linfo;', which is assigned to thd->current_linfo, however
this variable goes out of scope and is destroyed before clean
thd->current_linfo.

The problem is solved by moving 'LOG_INFO linfo;' to function scope.
