Travis Vitek commented on STDCXX-886:
-------------------------------------
As I mentioned in STDCXX-846, I know there are workarounds. I suggested either
skipping these 'bad' locales or to terminate the stream with traits::eof(). It
would also work to limit the length of the input sequence as you have just
proposed. Unfortunately that doesn't fix the more general case shown in the
test program shown in STDCXX-846.
> [HP aCC 6.16] SIGABRT in 22.locale.num.get.mt

> Key: STDCXX-886
> URL: https://issues.apache.org/jira/browse/STDCXX-886
> Project: C++ Standard Library
> Issue Type: Bug
> Components: Tests
> Affects Versions: trunk
> Environment: $ uname -sr && model && aCC -V
> HP-UX B.11.31
> ia64 hp server rx2660
> aCC: HP C/aC++ B3910B A.06.16 [Nov 26 2007]
> Reporter: Martin Sebor
> Fix For: 4.2.2

> The test fails with {{SIGABRT}} in nightly builds but it look like a thread
> safety problem because it fails even with a single thread. Here's the output
> including the stack trace:
