[jira] Created: (STDCXX-512) std::valarray computed assignment
operators don't compile with a user-defined class
std::valarray computed assignment operators don't compile with a user-defined class
-----------------------------------------------------------------------------------
Key: STDCXX-512
URL: https://issues.apache.org/jira/browse/STDCXX-512
Project: C++ Standard Library
Issue Type: Bug
Components: 26. Numerics
Affects Versions: 4.1.3
Reporter: Martin Sebor
The program below fails to compile because the valarray computed assignment operators make use of operator@ (T, T) instead of the corresponding computed assignment operators defined by T (i.e., T::operator@(T)).
$ cat u.cpp && make u
#include <valarray>
struct Value {
Value& operator*= (const Value&) { return *this; }
Value& operator/= (const Value&) { return *this; }
Value& operator+= (const Value&) { return *this; }
Value& operator-= (const Value&) { return *this; }
Value& operator%= (const Value&) { return *this; }
Value& operator^= (const Value&) { return *this; }
Value& operator&= (const Value&) { return *this; }
Value& operator|= (const Value&) { return *this; }
Value& operator<<= (const Value&) { return *this; }
Value& operator>>= (const Value&) { return *this; }
};
int main ()
{
std::valarray<Value> val;
val *= val;
val /= val;
val += val;
val -= val;
val %= val;
val ^= val;
val &= val;
val |= val;
val <<= val;
val >>= val;
}

[jira] Updated: (STDCXX-512) std::valarray computed assignment
operators don't compile with a user-defined class
Posted by "Martin Sebor (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/STDCXX-512?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Martin Sebor updated STDCXX-512:
--------------------------------
Severity: Compiler Error
Priority: Minor (was: Major)
Affects Version/s: 4.1.2
4.1.4
Fix Version/s: (was: 4.2)
4.2.1
It's unusual to instantiate std::valarray on a user-defined type, so setting Priority to Minor. Since the template hasn't changed added other 4.1.x versions to the list of Affected Versions. It's too late to fix this now so deferred for 4.2.1 (provided a compatible fix is possible).

> The program below fails to compile because the valarray computed assignment operators make use of operator@ (T, T) instead of the corresponding computed assignment operators defined by T (i.e., T::operator@(T)).
