Heap Corruption Dectected

After Normal block (#81) at 0x003f74c0 CRT detected that the application wrote to memory after end of heap buffer

which is not appeare in Release Mode ( it terminate itself sliently)

 

This is a typical memory leak:

 

Reason of my situation:

 

int total_lenth = 

6;

char *pstr = 

new 

char[total_lenth];

strcpy(pstr , 

"

abcdefg

");

//

Reason: store more than it could contain 

delete pstr;

//

error happen here

 

必须 “一个字节不差”
