Bug using pvPortMalloc

Hello, we have ported FreeRTOS on the ADUC7026 Microcontroller and have sucessfully  used pvPortMalloc from Heap_2.c for many purpose. But since we try to allocate memory for a certain Datastructure, it works correctly with the Keil simulator but abort when testing on the Ucontroller. Here is the datastructure. /*********************************************/ typedef struct txmsg {         struct txmsg    *next;  /* Next in linked list. */         ABCSP_TXMSG     *m;     /* The message (reference) itself. */         unsigned        chan:4; /* BCSP channel. */         unsigned        seq:3;  /* Sequence number. */         } TXMSG; /******************* And here the code using that datastructure * ********************/ void testCalloc(void){ TXMSG * m; m = ( TXMSG * ) malloc ( sizeof ( TXMSG ) ); if ( m ==(( TXMSG * ) NULL ) ) /*Panic*/ ; else {      m->chan=0;      } } /********** End of the code ******************/ We stepped with the Keil Debugger on the Heap_2.c pvPortMalloc code and found that the System allways abort when trying to call: /* Insert the new block into the list of free blocks. */                     prvInsertBlockIntoFreeList( ( pxNewBlockLink ) ); Please have even had a such problem ? Or do you have any solution for this? Thank you in advance. Emeric

Do you have portBYTE_ALLIGNMENT set correctly?
