One deterministic module has affine ranking function unknown-#memory_int-unknown[x_ref][x_ref] and consists of 8 locations. One deterministic module has affine ranking function org.eclipse.cdt.internal.core.dom.parser.c.CASTIdExpression@2ffda1ad and consists of 7 locations. One deterministic module has affine ranking function org.eclipse.cdt.internal.core.dom.parser.c.CASTIdExpression@2ffda1ad and consists of 8 locations. 2 modules have a trivial ranking function, the largest among these consists of 16 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 17.0s and 6 iterations.
