[jira] Updated: (STDCXX-619) purify reports array bounds read error

Posted by "Travis Vitek (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/STDCXX-619?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Travis Vitek updated STDCXX-619:
--------------------------------
Attachment: stdcxx-619.patch
Simply avoid the unnecessarily accessing the array inappropriately. I could have opted to add an else with a different assertion to keep the assertion count consistent, but that seems unnecessary.

[jira] Commented: (STDCXX-619) purify reports array bounds read
error in 25.remove test

Farid Zaripov commented on STDCXX-619:
--------------------------------------
I'd rather moved the rw_assert()'s into the for-loop body, instead of skipping them if !success.
So that rw_assert()'s will be invoked independently from the success value and iff the loop body was entered, instead of invoking the rw_assert()'s on !success.
Also I've added the two "success = true;" before loop, because the rw_assert()'s which follows that loop's may use the previous success value when the loop was iterated 0 times.
