+- Report failures in SQLGetDiagRec. This should warn on many silent errors.
+- Workaround issue with using SQLGetSubString with a large buffer on a DBCLOB
+  with locator by trimming from first instead of last null byte.
+- Workaround bug in SQL/CLI caused by unknown PTF, which causes a buffer
+  overflow with SQLGetData on char-like values. The PTF causing the regression
+  is unidentified, but workaround PTFs seem to exist, including SI75759. The
+  workaround will likely be kept until most no longer have the defective PTF.
