1173. Unclear specification of effects of signal handling

Section: 6.9.1  [intro.execution]     Status: C++11     Submitter: GB     Date: 2010-08-06

[Voted into the WP at the November, 2010 meeting.]

N3092 comment GB 7

The current wording of 6.9.1 [intro.execution] paragraph 6 could be read as saying that any signal would leave the program in an unspecified state after completing.

Proposed resolution (August, 2010):

Change 6.9.1 [intro.execution] paragraph 6 as follows:

When the processing of the abstract machine is interrupted by receipt of a signal, the values of objects which are neither

are unspecified during the execution of the signal handler, and the value of any object not in either of these two categories that is modified by the handler becomes undefined.
