The segfault issue goes away with 2.3.2, as mentioned above. This
discussion describes how to reproduce the issue using the unixODBC 2.3.0:
The point here...the concern...is really that the official Microsoft
certified unixODBC version is 2.3.0, a very old version with a known bug.
The documentation mentions that version repeatedly, and specifically states
that 2.3.1 is not supported. So the docs are really outdated, and I guess
the installation script is too because it requires additional manual
workarounds to use newer versions of unixODBC. Here are the Microsoft
This has been raised in several threads, and has been a known issue since
2012, but Microsoft has failed to certify or document use of newer versions
of unixODBC since then. Unless I'm just looking in the wrong place.
Here's another article that turned up in a search for the driver...once
again it describes use of unixODBC 2.3.0.
So the question is whether it's a good idea to advocate for the use of this
driver, which seems to be somewhat abandoned after several years. Has
anyone seen any statements from Microsoft that they're continuing to
support it? I've seen this discussed among users also on the Microsoft
