• Key: STDCXX-844
• Type: Bug
• Status: Open
• Priority: Minor
• Assignee: Unassigned
• Reporter: Martin Sebor
• Component/s: Test Driver
• Affects Version/s: 4.2.0
• Fix Version/s: 4.2.2

Environment

Sun Studio 12 (Sun C++ 5.9)
Solaris 10/AMD64

Description

When compiled with Sun C++ 5.9 in wide mode (with the -m64 option) the 0.strncmp test fails two subtests. This happens both with 4.2.0 and the head of trunk. No other platforms seem to be affected. Suspect a compiler bug.
