[Moved to DR at 4/01 meeting.]
Is it permitted to jump from a handler of a function-try-block into the body of the function?
Clause 14 [except] paragraph 2 would appear to disallow such a jump:
A goto, break, return, or continue statement can be used to transfer control out of a try block or handler, but not into one.
However, 14.4 [except.handle] paragraph 14 mentions only constructors and destructors for the prohibition:
If the handlers of a function-try-block contain a jump into the body of a constructor or destructor, the program is ill-formed.
Is this paragraph simply reemphasizing the more general restriction, or does it assume that such a jump would be permitted for functions other than constructors or destructors? If the former interpretation is correct, it is confusing and should be either eliminated or turned into a note. If the latter interpretation is accurate, Clause 14 [except] paragraph 2 must be revised.
(See also issue 98.)
Proposed resolution (04/01):
Delete 14.4 [except.handle] paragraph 14.
