I didn't have any chance to test on sid and I'm reasonably ignorant
about Debian sysadmin tasks to avoid damages to a reasonably working
workstation to overwrite php with a self compiled one.
Anyway I got struck by a similar problem with sybase_* on sarge
[i386]. The common link may be FreeTDS (I notice you're also the
maintainer of freetds).
Infact using sqsh I experience the same problem.

One problem seems related to datetime fields.
Even a simple:
select top 1 datetimefield from table;
*always* end up in a segfault.


Another problem seems related to large dataset returned.
It is more frequent if a single record is large rather than if there
are many recordsets returned. I still didn't succeed to make this
problem completely reproducible and I haven't quantified "large".
This problem seems sporadic.

thx
