2093. Qualification conversion for pointer-to-member handler matchingSection: 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
...
the handler is of type cv T or const T& where T is a pointer or pointer to member type and E is a pointer or pointer to member type that can be converted to T by either or both of
a standard pointer conversion (7.3.12 [conv.ptr]) not involving conversions to pointers to private or protected or ambiguous classes
a qualification conversion (7.3.6 [conv.qual]), or
the handler is...
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.
