So it just leaks any memory that's been allocated by
the partially-run constructor?
If you're referring to resources in general that a constructor (in the
C++ sense) allocates - memory, file descriptors, whatever - then it's up
to the constructor to release those resources before throwing the
exception should something fail. Destructors are not executed for
objects that were not constructed.
If the constructor is not written to that standard, then yes - it will
leak resources.
The memory allocated for the _object_ itself will be released though.
