An access violation error occurs when you run a Visual C++ 2010 application that is built for an x64 platform if an optimization compiler option is enabled
Article ID: 2485545 - View products that this article applies to.
Consider the following scenario:
This issue occurs because the compiler-generated code calls an instruction that requires a data buffer aligned in 16-byte blocks. For example, the code calls a MOVAPD or MOVDQA instruction. However, the data buffer may be unaligned. Therefore, an access violation occurs when the application uses this instruction to try to write an optimized local variable into an unaligned data buffer.
