[gecode-users] Freeze with MSVC 2015 optimized build

[Christian Schulte]

Hi Filip,

If you tell me which script you tried, I can try here (even though Gist
works for me with MSVC 2015 and Qt-5.5.0, using the trunk).

Cheers
Christian

So in the end I finished using the pre-built version of Qt and I'm now able
to run the script in Gist (Gist::dfs). The issue is still there.  I ran
'Next Solution' - this apparently runs the search in a separate thread but
never finishes (and 'Stop' does not stop the search, you have to kill the
program). Inspecting the nodes one by one freezes the program during the 3rd
expansion, and in this case the program stops responding altogether.

So my guess is this is really some tight loop somewhere in Gecode (maybe
caused by a new optimization or bug in the new compiler?)

Cheers,
Filip
