Travis Vitek reassigned STDCXX-450:
-----------------------------------
Assignee: Travis Vitek
> std::use_facet<std::num_put>() not thread safe
> ----------------------------------------------
>
> Key: STDCXX-450
> URL: https://issues.apache.org/jira/browse/STDCXX-450
> Project: C++ Standard Library
> Issue Type: Bug
> Components: 22. Localization, Thread Safety
> Affects Versions: 4.1.2, 4.1.3, 4.1.4
> Environment: Linux
> Reporter: Martin Sebor
> Assignee: Travis Vitek
> Priority: Blocker
> Fix For: 4.2
>
> Attachments: 22.locale.num.put.mt.html
>
>
> The 22.locale.num.put.mt thread safety tests aborts at runtime indicating
> that there is a thread safety issue in the locale implementation.
> Unfortunately, running the test through the Intel Thread Checker hasn't
> revealed the cause of the problem since the thread checker exits prematurely,
> most likely due to a bug in the tool itself (see below).
