John,
Thanks. That explains why only Windows appears broken.
So, is the intent to use GNC_DBD_DIR on Windows as well or should we fix
the code and not use GNC_DBD_DIR to work around the issue on Mac?

It doesn’t affect the Mac Bundle because that defines GNC_DBD_DIR to point to
the bundle’s Resources/lib/dbd in the environment file.
Mingw64 doesn’t provide libdbi so it’s built by jhbuild. We set the dbd-driver
directory to the installation prefix,

I've been trying to understand why this hasn't been an issue on the other
platforms that have been on libdbi 0.9.1 for sometime. The generic bug was
introduced 2 years ago (commit b011c81). I suspect the issue isn't seen on
Linux where libdbi is installed in the system location or on a Mac build
machine. I think the issue should appear on non-build Macs but, of course, the
issue won't be apparent to a user unless they aren't using the xml format.

I maybe wrong about the c:\libdbi\lib\dbd folder as there are compile time
definition that will override the location which appears to be something like
/mingw32/lib/dbd but that should still typically miss in a typical user's
gnucash installation.
Setting GNC_DBD_DIR to something like C:\Program Files (x86)\gnucash\lib\dbd
should work around the issue.

Hi John,
I suspect the Windows nightly builds have not been properly supporting
databases since libdbi was updated to 0.9.1 on October 5th unless the drivers
are in the c:\libdbi\lib\dbd folder or the folder to which the GNC_DBD_DIR
environment variable is set.
For example, attempt to save as sqlite3.
It appears there is a generic bug in gnc_module_init_backend_dbi() when
HAVE_LIBDBI_R is defined. Specifically, when the initial dbi_initialize_r()
returns no drivers, the dbi_instance variable is still set.
So, instead of:
#if HAVE_LIBDBI_R
if (dbi_instance)
return;
#endif
the code should be:
#if HAVE_LIBDBI_R
if (dbi_instance)
{
dbi_shutdown_r (dbi_instance);
dbi_instance = nullptr;
}
#endif

Sherlock
