[Intel C++ 8.1/SuSE/AMD64] std::time_put thread safety problem

• Key: STDCXX-498
• Type: Bug
• Status: Resolved
• Resolution: Cannot Reproduce
• Priority: Major
• Assignee: Travis Vitek
• Reporter: Martin Sebor
• Component/s: 22. Localization
• Affects Version/s: 4.1.3
• Fix Version/s: 4.2.1

Description

Moved from Rogue Wave Bugzilla: http://bugzilla.cvo.roguewave.com/show_bug.cgi?id=1708 (note the name of the test is now 22.locale.time.put.mt.cpp).

tests/stdlib/locale/time_put_mt seems to have a thread safety issue
where a local name is corrupted and causes the test to fail.

Should look at STDCXX-456 at the same time.

Assigned to Travis and scheduled for 4.2.1.
Set Severity to Runtime Error.

I haven't been able to reproduce this failure in manual builds, and I'm not seeing it in automated testing either.
