[Bug 2003003] Re: unixODBC crashes when ODBC trace is enabled

[freemine xu]

the same problem here with steps as follows to reproduce
1. sudo apt install unixodbc
2. sudo apt install unixodbc-dev      # this might not be related
3. adding below section in /etc/odbcinst.ini
   [ODBC]
   Trace=yes
   TraceFile=/tmp/blabal.log
3. install any ODBC driver, such as that for mysql
4. isql -v <DSN for datasource>       # NOTE: must add -v to enable `verbose` mode
5. afdsfasdfsdf;                      # any statement that would generate failure SQLxxx call
then, you would get this:
*** buffer overflow detected ***: terminated
Aborted (core dumped)

Title:
  unixODBC crashes when ODBC trace is enabled

Status in unixodbc package in Ubuntu:
  Incomplete

Bug description:
  The package unixODBC 2.3.9-5, that installs by default on Ubuntu 22.04
  contains a crash. If ODBC trace is enabled
  (https://www.easysoft.com/support/kb/kb00945.html) unixODBC will crash
  when calling GetDiagRec(). It reports a buffer overflow while calling
  a _sprintf. Newer version of unixODBC, 2.3.11, does not contain this
  bug (I've built one from source on my 22.04 VM).
