View all issues with C++11 status.
The thread safety std::uncaught_exception() and the result of the function when multiple threads throw exceptions at the same time are unspecified. To make the function safe to use in the presence of exceptions in multiple threads the specification needs to be updated.
[ Resolution proposed by ballot comment ]
Update this clause to support safe calls from multiple threads without placing synchronization requirements on the user.
[ 2010 Batavia Concurrency group provides a Proposed Resolution ]
[ Adopted at 2010-11 Batavia ]
Change 99 [uncaught] p. 1 as follows:
Returns: true after
an exception object (15.1) until a handler for the exception (including unexpected() or terminate())
is activated (15.3). [ Note: This includes stack unwinding (15.2). — end note ]
