I've been upgrading some Windows servers from PostgreSQL 8.3.18 to 9.2.4. Along with that I upgraded psqlODBC for the Windows clients from 8.0x.xxxx to 09.01.0200. All was fine until I had a customer who could consistently get a gpf in psqlodbc35w.dll when doing an export. Getting a copy of their database, I could reproduce as well. Trying different driver versions, I've found no crashes with the 8.0x psqlODBC series, but I can reproduce the gpf starting with 09.00.xxxx through the latest 9.01.02?? that I compiled yesterday (2013/04/20) from the git repository. I've used UseDeclareFetch=1 and Fetch=100 since I started with PostgreSQL back in 2008. Now with the 09.xx.xxxx drivers I don't get a crash if I: 1. Set UseDeclareFetch=0 or 2. Set UseServerSidePrepare=1 I've got a 31MB mylog file (zipped) of an entire client session. I can uploaded somewhere if that would help The bulk of that could be stripped-out; probably just the first and last 1000 lines are relevant. The actual sql is doing an update one record at a time of a numeric(14,0) value. It updates the first two records, executes a fetch, then crashes (when UseDeclareFetch=1 and UseServerSidePrepare=0). These are the last lines in mylog before the gpf occurs: [14028-1870.117][SQLExtendedFetch][14028-1870.117]PGAPI_ExtendedFetch: stmt=03988330 rowsetSize=20 [14028-1870.117]SQL_FETCH_NEXT: num_tuples=500, currtuple=460, rowst=460 [14028-1870.118]PGAPI_ExtendedFetch: new currTuple = 479 [14028-1870.118]fetch_cursor=1, 054FEF28->total_read=500 [14028-1870.118]**** SC_fetch: non-cursor_result [14028-1870.118]fetch: cols=42, lf=0, opts = 039883B8, opts->bindings = 03A36758, buffer[] = 03C607C8 [14028-1870.119]type = 23, atttypmod = -1 Obviously I can start using UseServerSidePrepare=1, but I'm concerned that would be masking a bug that should be addressed.
