System Configuration
---------------------
   Architecture (example: Intel Pentium)         : AMD Athlon

   Operating System (example: Linux 2.0.26 ELF)  : RH 7.1

   PostgreSQL version (example: PostgreSQL-7.1.3): PostgreSQL-7.1.3

   Compiler used (example:  gcc 2.95.2)          : gcc-2.96-97.1 (Used
pre-build binaries)


FULL description of your problem:
------------------------------------------------
We have ODBC application that is currently running on top of commercial
Solid and Sybase databases.With some fixes I got this application to
also work on PSQL on top of W2K. Now I'm trying to get the app to work
in Linux with libiodbc-3.0.5-1 and postgresql-odbc-7.1.3

However there seems to be problem with SQLPutData call. This was already
a problem in W2k with PSQL (ODBC 07_01_0006), and you can see the ugly
fix I made in the code. In Linux the same fix causes the program to get
segmentation fault in st.ParamData call. If I remove the fix the final
st.PutData call in the loop fails.

I think this could be problem related to odbc somehow, but I really
don't know.

/**** Code with the problem **************************
     else
     {
         char buf[256];
         int got;
         pos = 0;
         do
         {
        // This copies data to buffer buf nothing more
             got = data->GetData( pos, buf, sizeof(buf) );

#ifdef PSQL
#ifdef WIN32
        if (got == 0)
          break;
#endif //WIN32
#endif //PSQL

        st.PutData( buf, got );
             pos += got;
         } while( got > 0 );
     }
     rc = st.ParamData( &pos );
