Martin Sebor commented on STDCXX-840:
-------------------------------------
The {{SIGABRT}} in the output above was the same problem as STDCXX-843. The
{{SIGSEGV}} is something different. Here's the stack trace:

> [Sun C++] SIGSEGV in 22.locale.codecvt.mt.cpp in LP64 with optimization
> -----------------------------------------------------------------------
>
> Key: STDCXX-840
> URL: https://issues.apache.org/jira/browse/STDCXX-840
> Project: C++ Standard Library
> Issue Type: Bug
> Components: Tests
> Affects Versions: trunk
> Environment: Sun C++/Solaris/
> Reporter: Martin Sebor
> Priority: Minor
> Fix For: 4.2.1
>
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> On Solaris/SPARC, when compiled with Sun C++ (any version) in LP64 mode with
> optimization on (-O) the test
> [22.locale.codecvt.mt.cpp|http://svn.apache.org/viewvc/stdcxx/trunk/tests/localization/22.locale.codecvt.mt.cpp?view=markup]
> abends with {{SIGSEGV}}.
> On Solaris/AMD64/LP64, the test also abends with {{SIGSEGV}} with
> optimization, but with {{SIGABRT}} without.
> When compiled with gcc 4.1.1 on Solaris the test runs successfully to
> completion.
> Since this test is new in 4.2.1 its failure is a regression.
