#pragma options ignprag
Instructs the compiler to ignore certain pragma statements.
This option is useful for detecting aliasing pragma errors. Incorrect aliasing gives runtime errors that are hard to diagnose. When a runtime error occurs, but the error disappears when you use ignprag with the -O option, the information specified in the aliasing pragmas is likely incorrect.
