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.
