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: [email protected]
Reporter: [email protected]
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_init
>If a void initialized variable's value is used before it is set, the behavior
>is undefined.
