Subject [jira] Commented: (STDCXX-886) [HP aCC 6.16] SIGABRT in 22.locale.num.get.mt
Date Fri, 18 Apr 2008 18:38:22 GMT

    [ https://issues.apache.org/jira/browse/STDCXX-886?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12590555#action_12590555
] 

Martin Sebor commented on STDCXX-886:
-------------------------------------

I just discovered that the test sets up the input sequence to be {{NUL}}-terminated. Replacing
the {{RW_COUNT_OF()}} macro in calls to {{MyStreambuf::pubsetg()}} with {{Traits::length()}}
seems to fix it. Unless you set it up that way on purpose I'll go ahead and commit this change.

> The test fails with {{SIGABRT}} in nightly builds but it look like a thread safety problem
because it fails even with a single thread. Here's the output including the stack trace:
