------------------------------+---------------------------------------------
 Visual Studio has a memory leak detector that can be used in debug mode to
 track malloc/new memory allocations. I activate it most of the time on my
 software. With the current version of Ipopt trunk, a memory leak is
 detected in the file IpMa57TSolverInterface.cpp.

 Basically, it seems the compiler does not release the memory of the two
 arrays of strings ma57_err_msg and ma57_wrn_msg. If I declare explicitly
 the size of the arrays with:
   std::string ma57_err_msg[18] = {" ...
 instead of
   std::string ma57_err_msg[] = {" ...
 no leak is reported.

 I am not sure if it is a real memory leak or a problem/bug in the MS
 runtime, but I think it is worth checking, and anyway easy to correct (for
 instance with an explicit array size, or by using a C++ std::vector
 instead of an array).
