Martin Sebor reassigned STDCXX-423:
-----------------------------------
Assignee: Martin Sebor
> LIMITS.cpp assumes integers with no padding bits
> ------------------------------------------------
>
> Key: STDCXX-423
> URL: https://issues.apache.org/jira/browse/STDCXX-423
> Project: C++ Standard Library
> Issue Type: Bug
> Components: Configuration
> Affects Versions: 4.1.2, 4.1.3, 4.2.0
> Environment: unknown
> Reporter: Martin Sebor
> Assignee: Martin Sebor
> Priority: Trivial
> Fix For: 4.2.1
>
>
> The LIMITS.cpp config test tries to determine exact-width integer typese (the
> equivalent of things such as int32_t) but it fails to consider the fact that
> all integer types other than unsigned char may have padding bits that
> contribute to their size but not to their range (i.e., there may be two or
> more distinct bit patters that represent the same value, or bit patterns that
> do not correspond to any value at all). This is only an issue in theory since
> we know of no architecture with such a representation.
