Bug ID: 108951
Summary: std::valarray doesn't support extended alignment
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
Target Milestone: ---
Memory for valarrays is obtained via:
template<typename _Tp>
inline _Tp*
__valarray_get_storage(size_t __n)
{ return static_cast<_Tp*>(operator new(__n * sizeof(_Tp))); }
// Return memory to the system
inline void
__valarray_release_memory(void* __p)
{ operator delete(__p); }
This will be wrong for types with extended alignments.
We should either copy the code from std::allocator::allocate, or just use
std::allocator<_Tp> here.
