[vtk-developers] AMREnzoReader valgrind defects

[Bill Lorensen]

The subject has had valgrind issues for a while:

A quick look shows that some of its methods are returning cstr
pointers to local std::strings which is not correct. Perhaps they
should be returning std::string"s instead?

For example:

const char * GetEnzoDirectory( const char * path )
{
//  int start;
//  GetEnzoMajorFileName( path, start );
  std::string mydir = vtksys::SystemTools::GetFilenamePath( std::string(path) );
  return mydir.c_str( );
}
