char* dll调用问题

[houdongfeng]

VC dll中
　　 char *tmp;
tmp = new char[13];
　　　　．．．
　　　　return tmp
调用中
　　 char *rr;
strcpy(rr,icprint(2007,6,15));

执行到strcpy(rr,icprint(2007,6,15));就报错
怎么办

[luohongming]

char *rr;
strcpy(rr,icprint(2007,6,15));
rr还未分配内存，加rr=new char[???];memset(rr,0,???);

报错

Debug Error

The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.
