SYMPTOMS
Under low memory conditions, Microsoft Visual C++ .NET applications may receive an access violation and crash suddenly. The stack trace of the crash will be the following: 01 MODULE!std::ios_base::_Callfns+0x9 02 MODULE!std::ios_base::_Tidy+0xb 03 MODULE!std::ios_base::~ios_base+0x29



CAUSE
This problem occurs because the required initialization in the C++ Runtime Library does not occur because of memory allocation failures.
