Detailed Description

Initial code from https://stackoverflow.com/questions/11828539/elegant-exception-handling-in-openmp

The implementation does not guarantee, that while the exception is being checked for nullptr in the bool-conversion operator, the capture is not changing the pointer. This might lead to an exception being lost if there are two exceptions thrown simultaneously.
