2093. Qualification conversion for pointer-to-member handler matching

Section: 14.4  [except.handle]     Status: CD4     Submitter: David Majnemer     Date: 2015-03-06

[Adopted at the February, 2016 meeting.]

The criteria for matching an exception handler in 14.4 [except.handle] paragraph 3 include a qualification conversion for a handler of pointer or reference to pointer type but not for a handler of pointer-to-member type. However, current implementations permit such conversions.

Proposed resolution (October, 2015):

Change 14.4 [except.handle] bullet 3.3 as follows:

A handler is a match for an exception object of type E if

Notes from the October, 2015 meeting:

This resolution should not be adopted as a Defect Report, only a change in the working paper for future revisions of the Standard, because it could silently change the behavior of well-defined programs in implementations that conform to the existing wording.
