The fix and the testcase have been pushed to odbc-2.0 as commit 34d583b7481dd38b1f9bceb6ec2d21e93d3642ce
The problem was that parser would think of \ that it escapes closing quote, even if it was escaped in its turn(i.e. if it represented the character in the string.

There is also need to care about NO_BACKSLASH_ESCAPES mode case, which will break parsing even this fix.

The fix is now revision 6a1619befbe800e3e7e27ca7dd8c87f2da0d3393, and it has been pushed to odbc-2.0. It's now, as well as the testcase, takes care of the NO_BACKSLASH_ESCAPES case.
