https://issues.dlang.org/show_bug.cgi?id=19580 Issue ID: 19580 Summary: [non-DMD] std.random seed bootstrap: don't count on reading an uninitialized variable being treated as an ordinary read Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: normal Priority: P1 Component: phobos Assignee: nobody puremagic.com Reporter: n8sh.secondary hotmail.com Calculations that transform an uninitialized variable may be omitted by LDC when optimizations are enabled. This is allowed by the standard so even though this does not affect DMD it should be avoided. See: https://github.com/ldc-developers/ldc/pull/2946#issuecomment-453828010 And: https://dlang.org/spec/declaration.html#void_initIf a void initialized variable's value is used before it is set, the behavior is undefined.--
