Обсуждение: psqlODBC crashes upon memory allocation failures
Hello, As I said here: http://www.postgresql.org/message-id/0A3221C70F24FB45833433255569204D1F4DB1CF@G01JPEXMBYT05 psqlODBC ignores memory allocation failure in a number of places. That causes the application crash due to NULL dereference. Actually, I ran into the crash of my 32-bit application under high load. The attached patch is the fix for it. I wish this will be included in the upcoming release. Regards, Takayuki Tsunakawa

It happens no-and-then by trivially scrolling forward + backward a result set with psqlodbc-09.05.0100 / postgresql30a.dll. Where i can get a patched version? Thanks for your help!

I'm suspicious if the patch is effective for your problem. Do your application run with useDeclareFetch option on? If so, the drivers on testing for 9.5.0101 at http://www.ne.jp/asahi/inocchichichi/entrance/psqlodbc/ have the possibility to fix your problem. regards, Hiroshi Inoue
