I'm sorry, I thought you meant to come back with another solution.

The improved PR does in fact solve the Issue.

I was able to reproduce the bug with the MySQL driver and the IBM i Access ODBC driver, so it would
either be a somewhat common driver bug or a bug in unixODBC?

Hmm, no feedback on the improved PR, which is an ugly hack anyway;
a "clean" solution would require to store pointers to allocated
handles in the db handles, what is not an option for any stable
version for BC reasons.  And actually I tend to regard this as
upstream bug (driver or driver manager).

Ugh, yeah, that patch can't work.  I'll have a closer look.
