Under construction
You may also wish to look at Common problems with C-with-Ease.
Some common problems:
Cause: Problematic destructors
It is possible that objects that you have created are being destructed
and that the destructors are accessing pointers that already have been
deleted or were never allocated. You should ensure that the objects
copy constructor and assignment operator behave appropriately,
especially if the object was used in a C++-with-Ease operation. It may
be that a pointer was passed to another process which then deleted it.
Cause: Incorrect marshalling.
Marshalling is used when passing parameters to functions and also when
sending objects through contexts to processes that do not share
memory with the sender. If the default marshal operators are used, then
the object is binary-copied. If it contains pointers or is variably
sized then problems will arise - either the remote process will not be
able to access through the pointer, or (worse) the other process will
modify or read some random part of memory. If an object contains
pointers then custom marshalling operators should be written.
Cause: Contexts not using context marshalling
Context handles (what an Ease programmer holds) contain pointers to
structures which hold a set of pointers to functions which marshal,
unmarshal, and call the appropriate constructors and destructors. If a
context does not use context marshalling, then these become shared
between separate context handles and multiple deletes of a single object
may occur.
