ext/odbc builds the result string from the driver-reported vallen, which on truncation exceeds the bound displaysize+1 buffer (SQL_SUCCESS_WITH_INFO), over-reading heap into the returned value. Clamps the length to the bound capacity at the three fetch sites. Reproduces with the SQLite3 ODBC driver; the test skips without it.

Fixes #22668
