Description
A user reported obvious memory leak when solving many MIP problem with a fresh CplexMip instance for each. In addition valgrind report the following on CplexMip:
==10084== Conditional jump or move depends on uninitialised value(s) ==10084== at 0x8104C32: lemon::CplexEnv::~CplexEnv() (cplex.cc:66) ==10084== by 0x81051C8: lemon::CplexBase::~CplexBase() (cplex.cc:94) ==10084== by 0x8108C8E: lemon::CplexMip::~CplexMip() (cplex.cc:880)
The reason is that the constructor of CplexEnv does not initialize the target of the _cnt pointer when it is allocated.
