Tool/software:
Using SDK-7 , application uses the heapMem with gateMutex:
With the heapsize configured to : HEAPSIZE = 0x10000; and plenty of space remaining the function fails to free memory. This never happens on every free call because the same function allocates(Memory_alloc) memory and free it three times during the function call.
Debugging into the function free(ptr);, i found that the size parameter in the below function is corrupted(536892040) and calls: HeapMem_freeUnprotected.
/*
* ======== Memory_free ========
*/
void Memory_free(IHeap_Handle heap, void * block, size_t size)
{
if (heap == NULL) {
heap = Memory_defaultHeapInstance;
}
heap->free(heap, block, size);
}
before crashing:
Question: this happens because the application is calling Memory_alloc and uses free() to free? previously, I was using malloc and that was causing crash.
