Description:
When requesting debug status output with
mysqladmin debug
the output in the error log (assuming that mysqld_safe was used)
seems to be truncated at first as the mallinfo() related part
is missing, this part will only show up in the error log when
debug is called a 2nd time. This makes the missing part of the
first invocation appear but then again the mallinfo() output
for the 2nd call is missing
How to repeat:
Issue "mysqladmin debug", check output in mysql error log for the "Memory status:"
section ...
Suggested fix:
add an extra fflush(stdout) at the very end of mysql_print_status() in sql/sql_test.cc

message:
Bug#13608112 - 64048: MYSQL_PRINT_STATUS() MISSING FINAL FFLUSH()
Analysis:
While printing debug information, memory related information and event
related information were written to buffer after flushing it. Because of this,
these information were getting printed when we do the next flush.
Fix:
Instead of calling fflush() before writing memory and event
information, calling it after memory and event information.
I suppose it will be fixed by the current activity of merging bugfixes from 5.6.
Fixed in my 10.0 tree. Will be pushed shortly
