c++ - Exe binary crashes only outside IDE -

an opencv1.0 project uses cvblob structure lot (functions parameters, lists of blobs, etc).

struct cvblob{     float   x,y,w,h;     int     id; } 

i added members success inside vc9 project, until found out binary couldn't run outside ide in release mode. crashes during destruction somewhere (it doesn't when executed inside project).

the new structure:

struct cvblob{     float   x,y,w,h;     int     id,myint; //works fine.     double* mydouble; //crushes outside visual studio. } 

during rutime, mydouble used array:

blob.mydouble=new double [10]; 

any generic advise, before dive large source code?

edit: debug runs outside ide.

edit2: cvseq used main blob list container: cvseqpush(cvseq*,cvblob*), cvseqremove(cvseq*,int). undefined behavior here?

shouldn't able extend cvblob structure , add own constructor , destructor manage memory mydouble?

  struct mycvblob : cvblob {        double* mydouble;        // initialize mydouble null in constructor        mycvblob() {           mydouble = null;        }        // free memory pointed mydouble if in use        virtual ~mycvblob() {           if(mydouble) {              delete [] mydouble;           }        }   };    mycvblob blob;   blob.mydouble = new double[10];
