     Type:  defect  |     Status:  new
 Priority:  normal  |  Milestone:
Component:  Master  |    Version:  stable/5.6 (SVN)
 Keywords:          |
--------------------+------------------------------
 Please see the two attached files "test_milp.MPS" and "milp.c". The c file
 adds a new column to a very basic problem. The new problem should only
 have an added "z" variable in the objective. For this particular problem,
 (after compiling the example and ./exe_name -F test_milp.MPS) symphony
 terminates with seg fault. For another problem tested, it returns an
 incorrect problem, mixing up columns and values. The result of valgrind
 (when failing with seg fault) is

 ==9799== Invalid read of size 8
 ==9799==    at 0x4C2A7E8: memcpy (mc_replace_strmem.c:838)
 ==9799==    by 0x4157B6: sym_add_col(SYM_ENVIRONMENT*, int, int*, double*,
 double, double, double, char, char*) (master.c:4129)

 This result is obtained by configuring 5.6 stable (or trunk) as follows:

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