Ok, unfortunately this backtrace isn't sufficient to track down the bug, due
to a lack of debugging symbols in php5-odbc.  Could you try rebuilding php5
with DEB_BUILD_OPTIONS=nostrip and see if that helps get a more precise
backtrace?

If you aren't able to, perhaps one of the other php maintainers could help
with this.
