c++ allocator error in ios - c++

Question

My iPhone app is using a 3rd party software written in c++.
I have received many error reports with such a stack trace:
0 libsystem_kernel.dylib
__pthread_kill + 8
1
libsystem_pthread.dylib
pthread_kill + 58
2
libsystem_c.dylib
abort + 76
3
libc++abi.dylib
abort_message + 74

MyApp
new_allocator.h line 91
void std::vector<unsigned char, std::allocator<unsigned char> >::_M_range_insert<char const*>(__gnu_cxx::__normal_iterator<unsigned char*, std::vector<unsigned char, std::allocator<unsigned char> > >, char const*, char const*, std::forward_iterator_tag)
This is the relevant part of the code:
void FileDownloadClient::__OnDataArrival( const char * pData ,int nDataLen )
{
....
m_received_data.insert(m_received_data.end(),pData,pData+nDataLen); //Offending line that crashes
....
}
m_received_data is declared as an instance variable of type std::vector<uint8>
Does anyone know what might be the problem or how to approach this problem at all?
Let me know if you need other information. Thanks a lot for any help!
