Bug ID: 83662 Summary: std::aligned_alloc() not available Product: gcc Version: 8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: nico at josuttis dot de Target Milestone: --- C++17 is based on C11, which now standardizes aligned_alloc(). However, <cstdlib> does not provide it under namespace std: #include <cstdlib> int main() { auto p1 = std::malloc(100); // OK auto p2 = aligned_alloc(64, 100); // OK auto p3 = std::aligned_alloc(64, 100); // ERROR } Error: prog.cc: In function 'int main()': prog.cc:7:18: error: 'aligned_alloc' is not a member of 'std' auto p3 = std::aligned_alloc(64, 100); // ERROR ^~~~~~~~~~~~~ prog.cc:7:18: note: suggested alternative: 'align_val_t' auto p3 = std::aligned_alloc(64, 100); // ERROR ^~~~~~~~~~~~~ align_val_t
