Topic: exit should not invoke cancellation cleanup handlers or per-thread data destructors
Relevant Sections: XSH exit------------------------------------------------------------------------
7 Defect Report concerning (number and title of International Standard or DIS final text, if applicable):
The System Interfaces volume of IEEE Std 1003.1-2001
------------------------------------------------------------------------
8 Qualifier (e.g. error, omission, clarification required):
1. Error
------------------------------------------------------------------------
9 References in document (e.g. page, clause, figure, and/or table numbers):

Reference xshbug2.txt ERN 41
------------------------------------------------------------------------
10 Nature of defect (complete, concise explanation of the perceived problem):
"exit()" should behave the same as _exit() or _Exit() with respect to cancellation cleanup handlers and per-thread data destructors.
------------------------------------------------------------------------
11 Solution proposed by the submitter (optional):
Replace Threads terminated by a call to _Exit() or _exit() shall not invoke their cancellation cleanup handlers or per-thread data destructors. with Termination of a process shall not invoke any thread cancellation cleanup handlers or per-thread data destructors.
------------------------------------------------------------------------
Interpretation response ------------------------ The standards states the requirements for exit(), and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor.
Rationale: --------- None.
Notes to the Editor (not part of this interpretation): ----------------------------------------------------- exit() should be described on a separate page that explains at the end that exit() inherits the behavior described separately for _exit()
