While trying to compile GtkD dmd was trapped in an infinite loop.

It happens when running 'dmd -v -release -O -inline -m64 -Isrc -c
src/gtkc/gtk.d -ofsrc/gtkc/gtk.o' and doesn't occur when removing -inline.

Unfortunately I couldn't reduce it yet, so here's the original:

            else if (OTbinary(op))
            {
                if (OTrtol(op) && ERTOL(n))
                {   accumaecpx(n->E2);
                    accumaecpx(n->E1);
                }
                else
                {   accumaecpx(n->E1);
--->                accumaecpx(n->E2);
                }
                if (OTassign(op))               // if assignment operator
                    t = Elvalue(n);
            }
