Summary:                    Asterisk crash on ODBC /usr/lib/libodbc.so.1 and
/lib/i686/cmov/libc.so.6
Description: 
Hi,

 On quite heavy load I expirience Asterisk crash. 
Asterisk 1.6.1.19 + following ODBC version

ii  libiodbc2                            3.52.6-2                   iODBC
Driver Manager
ii  libmyodbc                            3.51.15r409-4              the
MySQL ODBC driver
ii  libodbcinstq1c2                      2.2.11-16                 
Qt-based ODBC configuration library
ii  odbcinst1debian1                     2.2.11-16                 
Support library and helper program for acces
ii  unixodbc                             2.2.11-16                  ODBC
tools libraries
ii  unixodbc-bin                         2.2.11-16                 
Graphical tools for ODBC management and brow
ii  unixodbc-dev                         2.2.11-16                  ODBC
libraries for UNIX (development files)


I'm using ODBC quite hard for dialplan (checking permissions, setting up
database variables for Queues, sip realtime, etc)
Same I saw in 1.6.1.18 - I upgraded yesterday to .19 and this did not
solve issue.
