[Symphony] Usage model of sym api's

[Peter Moceyunas]

Hi,

Does the symphony api's support the following  sequence in which 
sym_solve() is call twice on the same "env" ?

env = sym_open_environment();
sym_parse_command_line(env, argc, argv);
sym_load_problem(env);
sym_solve(env);
.
.
add a row and modify the objective function of the "env"
.
sym_solve(env)



When I run this code, I  observe memory leaks

These leaks got me thinking that maybe calling sym_solve() twice is not 
supported ....
If it is supported, then any ideas on where to look to patch up this 
memory leak ?
I am using version 5.1.7 of symphony ....
