Hi, (earlier posting on D.learn, but better test included here)...
dmd.2.067, dmd.2068 (64bit linux) import std.container: SList; void main() { SList!int tmp=( 4 ); SList!int tmp1; // Ensure tmp is empty tmp.removeAny(); assert( tmp.empty == true ); // Both tmp and tmp1 are empty // (however tmp1 is not internally initialised) tmp.insertAfter( tmp[], 3 ); // tmp1.insertAfter( tmp1[], 3 ); <====== asserts here. } core.exception.AssertError@std/container/slist.d(57): Assertion failure Changes in phobos mean that you cannot append to an _uninitialised_ empty singly linked list (you can, however, append to an _initialised_ empty linked list..... bug ? --ted
