#130: Incorrect solution (infeasibility reported)

----------------------+-------------------------
In both the trunk and 5.5 versions, when configured as default (i.e.,
../configure), SYMPHONY returns a finite optimal solution for the two
attached files (which matches with CPLEX's solutions).
However, when it is built with the following configuration:
../configure --enable-debug --enable-gnu-packages --enable-sensitivity-
analysis --enable-tests --enable-tm-tests --enable-draw-graph --with-
application
it reports infeasibility after producing errors in the form of
#####Error: LP objective value decrease from -215.080 to -215.116
Error! Told not to branch, but there are no new cuts or variables!
