Bug ID: 40978
Summary: Clang should raise a compile-error when co_await used
in a catch-block
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++2a
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected],

The Coroutines TS N4775 [expr.await] paragraph 2 states:
> An await-expression shall appear only in a potentially-evaluated expression
> within the compound-statement of a function-body outside of a handler (Clause
> 18).
However, current trunk version of clang does not emit a
compile-error/diagnostic when a co_await expression is used within a handler.

Clang should be detecting use of co_await within a catch block and raising a
compile-error that indicates this is not allowed.
