Hi,
I have a class which unzips an archive into a temporary
directory below the system temp folder. I want to delete this
temporary directory in the class's destructor, but when I call
rmdir there, I get an
core.exception.InvalidMemoryOperationError@(0)
Destructors are usually called by GC, during a GC cycle, so
allocating and deallocating memory is not allowed there. If some
function allocates, reallocates or deallocates, it will cause
this very error. This means you shouldn't use any functions in a
destructor that are not @nogc.
Solution in this case: call rmdir not from destructor.
