Sorry for the delayed response. The ODBC trace is down below...
I found another nugget of info.
I ran the same perl script on a WinNT box using same versions of Perl, DBI,
and DBD::ODBC but with native MDAC ODBC and SQL Server driver. I did not
encounter the segmentation fault, but my test case still failed. So, I may
have uncovered a bug in DBD::ODBC as well... though the segfault remains an
issue in the linux/unixODBC/FreeTDS environment.
DBD::ODBC has a test case of odbc call syntax which calls a procedure taking
1 integer input param and returning output. If that test case is modified
not to take an input var... it produces the same error as I show below.
I'll take this bug over to the DBI mailing list and Jeff Urlwin to see what
they make of it.
If I modify my stored procedure to match what works under DBD::ODBC (add an
input param to the stored proc), I finally have a success under WinNT w/
native ODBC and driver. However, I still get the same segfault under
linux/unixODBC/FreeTDS. Perhaps the differing error details under WinNT, etc
will assist in isolating the segfault...
In the interest of completeness...
