Bug #60031	main.plugin_auth fails in debug compilation
Submitted:	9 Feb 2011 1:12	Modified:	12 May 2011 23:06

Version:	5.6.2	OS:	Windows
Assigned to:		CPU Architecture:	Any

Description:
main.plugin_auth fails when compiled in debug mode.

the error is
Error:Run-Time Check Failure #3 - The variable 'lvl' is being used without being
initialized. At h:\bzr\tpms1\sql\log.cc:2212

How to repeat:
cmake ..
devenv mysql.sln /build debug
cd mysql-test
perl mysql-test-run.pl plugin_auth

Suggested fix:
initialize variable lvl before use

Currently, the source looks like:

int my_plugin_log_message(MYSQL_PLUGIN *plugin_ptr, plugin_log_level level,
                          const char *format, ...)
{
  char format2[MYSQL_ERRMSG_SIZE];
  int ret;
  loglevel lvl; <!--lvl NOT INITIALIZED
  struct st_plugin_int *plugin = (st_plugin_int *) plugin_ptr;
  va_list args;

  DBUG_ASSERT(lvl >= ERROR_LEVEL || lvl <= INFORMATION_LEVEL); <!-- lvl USED

change category to "General", FTS was mistake of course

I wasn't able to compile today source, however the test with a week older source fails with another error:

Miguel, I used lp:mysql-server (can't access anything else). Seems relatively fresh.

Thank you for the feedback.

I can not repeat nor described behavior, neither crash. Also looks like sql/log.cc was modified. Please upgrade to latest revision, try with it and inform us if problem still exists.
