 SYMPHONY is built with Cplex as the lp solver. When the optimal solution
 has all zero columns, setting the verbosity option to 5 (no other
 parameters), I get:

 Solution Found: Node 0, Level 0
 Solution Cost: 0.0000000000
 +++++++++++++++++++++++++++++++++++++++++++++++++++
 All columns are zero in the solution!
 +++++++++++++++++++++++++++++++++++++++++++++++++++
 sym_get_col_solution(): There is no solution!

 Symphony is configured with the following script.

 ../configure --enable-debug --enable-sensitivity-analysis --with-cplex-
 lib=-L/usr/local/CPLEX_Studio_125/cplex/lib/x86-64_sles10_4.1/static_pic/
 -l\
 cplex -lpthread -lm --with-cplex-
 incdir=/usr/local/CPLEX_Studio_125/cplex/include/ilcplex --with-lp-
 solver=cplex
