668. Throwing an exception from the destructor of a local static object

[Voted into the WP at the March, 2009 meeting.]

The destruction of local static objects occurs at the same time as that of non-local objects (6.9.3.3 [basic.start.dynamic] paragraph 1) and the execution of functions registered with std::atexit (paragraph 3). According to 14.6.2 [except.terminate] paragraph 1, std::terminate is called if a destructor for a non-local object or a function registered with std::atexit exits via an exception, but the Standard is silent about the result of throwing an exception from a destructor for a local static object. Presumably this is an oversight and the same rules should apply to destruction of local static objects.

Proposed resolution (September, 2008):

Change 14.6.2 [except.terminate] paragraph 1, fourth bullet as indicated, and add an additional bullet to follow it:

• when construction or destruction of a non-local object with static or thread storage duration exits using an exception (6.9.3.2 [basic.start.static]), or

• when destruction of an object with static or thread storage duration exits using an exception (6.9.3.3 [basic.start.dynamic]), or
