UMC H264 decoder heap corruption

[andrei_m]

Hi,

I'm getting heap corruption message while running simple_player example (release_ascii build configuration). I was playing the same video for 50-100 times in a row and then I've suddenly received a heap corruption message.

[cpp]HEAP[simple_player.exe]: Invalid Address specified to RtlFreeHeap( 010E0000, 010EBA18 )
Windows has triggered a breakpoint in simple_player.exe.

This may be due to a corruption of the heap, and indicates a bug in simple_player.exe or any of the DLLs it has loaded.
[/cpp]

I'm using IPP 6.0 update 2 and a sample package ver. 6.0.0.130.

Is this a known issue? has anyone solved it?

Thanks,
Andrei.
