Issue ID: 16046 Summary: ScopedAllocator does not set prev, causing segfaults Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: major Priority: P1 Component: phobos Assignee: nob...@puremagic.com Reporter: initrd...@gmail.com This code causes a segfault: ScopedAllocator!MmapAllocator alloc; auto foo = alloc.make!int(1).enforce; auto bar = alloc.make!int(2).enforce; alloc.dispose(foo); alloc.dispose(bar); // segfault here This is likely because ScopedAllocator.allocate does not set the prev pointer of the old root when prepending a new node, so prev will always be null. --
