See Prof. Ripley's message. RODBC is passing a buffer and buffer size to the ODBC driver, and that driver is overflowing the buffer. You could probably hide this bug by making the buffer larger, but the real fix is for the driver to take account of the buffer size it is being given.
1) How do you make the buffer bigger? Are we talking about increasing the -- --param=ssp-buffer-size=4 at compilation time? would that solve the problem, in your opinion?
I don't know. I wouldn't do that.
2) Why is this problem RODBC specific, if the problem is in the odbc driver?
Because the other packages pass bigger buffers, or generate different messages? I
do agree that RODBC passes buffer / buffer size, but why do other applications work and RODBC does not? If the problem was with the driver, then every other application linking to the same database through the same driver would have the same problem, unless the other applications pass the call (+ buffer / buffer size) in a different way.
Or if they ask the driver to do different things, or pass a different size of buffer, etc. The fact that this only occurs for RODBC suggests there's a problem there, but the fact that the driver is using sprintf on a limited size of buffer is far stronger evidence that the problem is in the driver.

Please, keep in mind I am just trying to solve a problem that other people may have, because I am using standard installation.
