<div dir="ltr">Hi,
<div>My CBC solver consistently crusher when it finds optimal
solution at root node after doing cuts generation.</div>
<div>I attach model, log and screenshot.</div>
<div>Model has ~20000 variables, most of them are "fixed" to
specific value by constraints, and only a fraction of ~20% is
to be solved.</div>
<div>I haven't tried 2.9.8 since i can't find the binary for
that version.
