gdamm1.3.4: segfault on data_model->get_n_rows();

[Daniel Holbach <dh mailempfang de>]

Hello everyone,

I hope I got the right list.

I'm using gdamm1.3.4 with gda1.1.99 and followed basically the examples
in the tarball. I use a PostgreSQL server (on another box) and use a
simple query, which works perfectly well in  pgaccess .

This ( int rows = data_model->get_n_rows(); ) crashes my project. For a
full context see 
http://cvs.berlios.de/cgi-bin/viewcvs.cgi/protosquared/protosquared/src/DBUtils.cc?rev=1.3&content-type=text/vnd.viewcvs-markup

Here the last lines of an ordinary  strace -run. Hope someone can help.
