I'm not looking for technical support; I'm just looking for a way to
report a bug and possibly help debug/resolve it. But as you know,
Digium's website gives FFA users no clear to contact them - even to
report problems. issues.asterisk.org has no selection for res_fax_digium
since it is not bundled with Asterisk. I call that willful blindness.

Don't get me wrong, I'm grateful for FFA and Asterisk in general - I
have several running 1.8.2 working correctly.

Alternatively, you can generating an unoptimized backtrace [2] and
posting the results to the mailing list, seeing if any member of the
community has also had an issue.

I didnt expect anyone on this list to be interested, but I suppose
you're right.

This weekend, i set up a new system running Asterisk 1.8.2 on Debian
5.0.7 where the benchmark told me to use
res_fax_digium-1.8.0_1.2.1-core2_32 (i also tried generic_32 but that
crashed as well).

Asterisk correctly detects the fax and transfers to the fax context. But
moments after ReceiveFax is called, asterisk crashes, with no tif
written where I've directed it to.

I have several files including backtraces and config files at
http://jeremy.kister.net/tmp/fax/

We have determined the cause of this problem; I'm sorry to say it's an incompatibility between releases that wasn't caught before the releases were made.

res_fax.c in Asterisk 1.8.2 contains some changes that make it incompatible with res_fax_digium modules compiled for Asterisk 1.8.0 and 1.8.1, which is what is causing this problem. For now, the res_fax_digium 1.2.x modules are only usable with Asterisk 1.8.0 and 1.8.1; there is a res_fax_digium 1.3.0 release currently being tested for release that is compatible with Asterisk 1.8.2 and later. We'll try to get it out as quickly as we can, and also update the download selector on the Digium website to indicate that the 1.2.x modules should not be used with Asterisk 1.8.2.
