ResetAndDestroy leaves?

Hi,

I have the following code in one of my classes definition:
class A {
...

typedef TBufC<MAX_LOG_OP_NAME> TOpName;
typedef struct {
TOpName m_opName;
TTime m_timeStarted;
} OpInfoStruct;

typedef CArrayPtrFlat<OpInfoStruct> OpInfoArray;
OpInfoArray m_operations;

....
};

In ~A() I call m_operations.ResetAndDestroy() which leaves unexpectedlly (I get the App closed message).

Any ideas?
Thanx

It's very unlikely that ResetAndDestroy leaves, because it doesn't end with L. What you are experiencing is probably a Panic, not a Leave. There are many reasons why it could panic. Most likey, that's double deallocation. Knowing the panic number/category would help. Check debug output from the emulator.

yarontt (not verified) Forum posts: 2019	ResetAndDestroy leaves? Found the problem. CArrayPtrFlat is derived from CBase and A is not. CArrayPtrFlat, assumes CBase operator new will zero it's memory. I changed m_operations to be a pointer member and it's ok now.
