Martin Sebor commented on STDCXX-826:
-------------------------------------
>From the stack trace it looks to me like the {{mbstate_t}} object that
>{{wfilebuf}} passes to the {{codecvt}} facet isn't properly initialized. We're
>pretty careful about initializing the stream state in the library so my
>suspicion is that the compiler isn't initializing it correctly. The
>[POD_ZERO_INIT.cpp|http://svn.apache.org/repos/asf/stdcxx/trunk/etc/config/src/POD_ZERO_INIT.cpp]
> config test tries to detect compiler bugs in this area. You might want to
>check to see if the test passes and if it does, that the compiler really does
>initialize PODs correctly (e.g., by tweaking the test according to how
>{{mbstate_t}} is being initialized in {{wfilebuf}} and elsewhere in the
>library -- look for the macros {{\_RWSTD_MBSTATE_T}} and
>{{\_RWSTD_NO_POD_ZERO_INIT}}.
> [Sun C++] SIGABRT in istringstream example
> ------------------------------------------
>
> Key: STDCXX-826
> URL: https://issues.apache.org/jira/browse/STDCXX-826
> Project: C++ Standard Library
> Issue Type: Bug
> Components: Examples
> Affects Versions: 4.2.0
> Environment: Sun C++/Solaris (both AMD64 and SPARC)
> Reporter: Martin Sebor
> Assignee: Eric Lemings
> Fix For: 4.2.1
>
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> When compiled with Sun C++ on Solaris, the example program
> [istringstream.cpp|http://svn.apache.org/repos/asf/stdcxx/trunk/examples/manual/istringstream.cpp]
> abends with SIGABRT at runtime. Observed intermittently in 11D, 15D, and 15S
> builds both in 4.2.0 results and in those with the head of trunk.
