CCS: Problem with Address in "MessageQ_alloc" and "MessageQ_free"

Tool/software: Code Composer Studio

Hii All,

I am working on messageQ communication between ARM to DSP. I am creating two tasks in DSP, in first task MessageQ_get is placed in while loop. In second task I have MessageQ_free, messageQ_alloc and MessageQ_put. Dsp load i am building with the CCS v6.

ARM code has one thread, inside the thread i have messageQ_get and messageQ_put and ARM load is building in linux terminal. 

I have declared messageQ variable as follow

#define MSGQ_ALLOC_SIZE   16

MessageQ_Msg aAllocBuf[MSGQ_ALLOC_SIZE];

NOTE: I have allocated a 512 bytes of heap for messages.

I have a buffer of 16 which is used to allocate, put and free the message. When I am trying to allocate for aAllocBuf [0] , aAllocBuf [1] and so till aAllocBuf [15] it is allocating with the same address  for all the indexes of a buffer. After four allocations, I am freeing the buffer and it is freeing the allocated memory for some random messages and DSP core0 is crashing by throwing an error as follow
