So I have confirmed that with the following options no actual plt file
is generated though the generation runs without fault. If I use a
simpler set of options a plt file does result. I am not sure what the
difference is. It does take over an hour to run on this though.
(replace <root-dir> and <some-other-dir> with real directories, of
course).

Opts = [{files_rec,["<root-dir>/repo/ktuo-0.4.0.1/ebin",
             "<root-dir>/repo/ewrepo-0.16.6.0/ebin",
             "<root-dir>/repo/ibrowse-1.4/ebin",
             "<root-dir>/repo/ewlib-0.7.4.0/ebin",
             "<root-dir>/repo/eunit-2.0/ebin",
             "<root-dir>/repo/sgte-0.7.1/ebin",
             "<root-dir>/repo/mnesia-4.4.2/ebin",
             "<root-dir>/repo/xmerl-1.1.8/ebin",
             "<root-dir>/repo/dialyzer-1.8.0/ebin",
             "<root-dir>/repo/gs-1.5.9/ebin",
             "<root-dir>/repo/hipe-3.6.6/ebin",
             "<root-dir>/repo/tools-2.6.1/ebin",
             "<root-dir>/repo/edoc-0.7.5/ebin",
             "<root-dir>/repo/compiler-4.5.2/ebin",
             "<root-dir>/repo/syntax_tools-1.5.4/ebin",
             "<root-dir>/repo/crary-0.2.0/ebin",
             "<root-dir>/repo/sasl-2.1.5.2/ebin",
             "<root-dir>/repo/uri-0.1.0/ebin",
             "<root-dir>/repo/kernel-2.12.2/ebin",
             "<root-dir>/repo/stdlib-1.15.2/ebin"]},
 {from,byte_code},
 {output_plt,"<some-other-dir>/_build/development/info/dialyzer_plt"}],
dialyzer:run(Opts).


However, If i do something trivial like

Opts = [{files_rec,["<root-dir>/repo/ktuo-0.4.0.1/ebin"]},
 {from,byte_code},
 {output_plt,"<some-other-dir>/_build/development/info/dialyzer_plt"}],
dialyzer:run(Opts).

A plt file is output as expected.

I have started going through and trying to see when dialyzer falls
over but its slow enough that its going to take me awhile.
