Let's consider a pseudo-code:
...
class JPEGDecoder
{
public:
JPEGDecoder()
{
...
};

~JPEGDecoder() <= set a break point here
{
...
};
...
};
...
void main( void )
{
JPEGDecoder *dec = new JPEGDecoder();
...
if( dec != NULL )
{
dec->Close();
delete dec; // Here it crashes, right?
}
...
}

When you're debugging try to step into delete C++ operator or set a break point in JPEGDecoder::~JPEGDecoder destructor in order to see what is going on there. I could assume that some resource is de-allocated twice.

Hello,

I can't stop in source of JPEGDecoder because I am using prebuilt libraries and UIC dlls. Can you try to reproduce the bug yourself?

Thanks.

Anyone?

Hi,

Do not use Close() here. ~JPEGDecoder calls Close() itself and there is double "delete m_jpeg".
This is fixed in 7.1.

Thanks for the confirmation that some issues are fixed.

Even without Close(), it still crashes.

Please take a look. This is your statement:

>>...This is all happening with dynamically linked UIC libs version 7.0.7...

This is Sergey Khlystov (Intel) statement:

>>...This is fixed in 7.1...

So, my question is did you upgrade the IPP library to version 7.1?

This is what you said:

"Do not use Close() here. ~JPEGDecoder calls Close() itself and there is double "delete m_jpeg". 
This is fixed in 7.1."

I understood that Close() calls delete m_jpeg and then since destructor calls Close() again it deletes already deleted pointer. Now, I tried removing Close() and leaving destructor calls it and the application still crashes. Did you mean to say that destructor calls delete m_jpeg as well as Close(). Meaning you had a big bug in your code. I'll try 7.1 and see if it works.

Thanks.

>>... I'll try 7.1 and see if it works.

Please try it. Here is a generic explanation of why it happens:

[ A version with a Bug ]
...
JPEGDecoder::~JPEGDecoder()
{
Close();
};

JPEGDecoder::Close()
{
DeallocateResource( pSomePointer );
};
...

[ A Correct version ]
...
JPEGDecoder::~JPEGDecoder()
{
Close();
};

JPEGDecoder::Close()
{
if( pSomePointer != NULL )
{
DeallocateResource( m_pSomePointer );
m_pSomePointer = NULL;
}
};
...
Note: In that case a "double" deallocation of some resource in m_pSomePointer simply impossible and such errors / bugs are very common.

Works with IPP 7.1. Thank you.

Thanks for the confirmation. You could also chage the title of the thread to [ FIXED in v7.1 ] Delete JPEG decoder crashes in Debug mode.
