I am getting a crash in the application in the libc. I dont know the reason, please help me if anyone knows about this crash.

I got this information in the website, but i dont have any shared resources (other than one .so file as library) and this didn’t resolved my issue.

    Thanks for your support.
    Actually in my code i was doing byte to short conversion which was corrupting the heap. I dont know how its getting corrupted even after allocating sufficient memory. After i moved this byte to short conversion to the native layer in the decoder, i am not getting crash now.

    thought it may help you guys. So, conclusion is not only for native, even when there is any corruption in memory in java layer also, i am getting the dump with libc. Which was misleading me to concentrate on native layer even though the problem was in Java layer.

    Thanks & Regards,
