ios: EXC_ARM_DA_ALIGN error in release build - ios

Question

I have a function in my application, that store data from buffer. It works fine in debug mode both device and simulator, but when I create .ipa and run it on device, I have EXC_ARM_DA_ALIGN error libstdc++.6.dylib std::string::_M_replace_safe(unsigned long, unsigned long, char const, unsigned long)
struct stMemoryBlock
{
stMemoryBlock(void* InData, int InSize)
{
data = InData;
size = InSize;
offset = 0;
};
void* data;
unsigned int size;
unsigned int offset;
};
//-----------------------------------------------
char* cDataCollector::TestMemoryThink(char* Buffer, int BufferSize, int TestOffset, int TestSize)
{
char* result = NULL;
if (TestOffset + TestSize <= BufferSize)
{
result = &Buffer[TestOffset];
}
return result;
}
//-----------------------------------------------------
bool cDataCollector::StoreBinaryData(void* DataBuffer, int DataSize)
{
bool result = false;
char* InBuffer = (char *)DataBuffer;
if (!mPreparedData && !mPreparedDataSize && !mMemoryMap.size())
{
unsigned int CountElements = 0;
int offset = sizeof(unsigned int);
if (DataSize >= sizeof(unsigned int))
{
// CountElements = *(unsigned int*)(&InBuffer[0]);
memcpy(&CountElements, InBuffer, sizeof(CountElements));
}
result = true;
for (unsigned int i = 0; (i < CountElements) && result; ++i)
{
std::string ThinkName ;
stMemoryBlock * MemoryBlock = NULL;
result = result && TestMemoryThink(InBuffer, DataSize, offset, 0) != NULL;
if (result)
{
size_t name_think_size = strlen(&InBuffer[offset]);
char* think_name = TestMemoryThink(InBuffer, DataSize, offset, 0);
result = result && (think_name != NULL);
if (result)
{
ThinkName = think_name;
offset += (name_think_size + 1);
}
}
this line cause an error:
ThinkName = think_name;
maybe I need another way to read a string from memory location that isn’t word (32-bit) aligned? please,help!
