https://issues.dlang.org/show_bug.cgi?id=24099 Issue ID: 24099 Summary: Immutable module variable can be initialized by multiple static constructors Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: snarwin+bugzilla gmail.com As of DMD 2.104.0, the following program compiles and runs to completion: --- import core.stdc.stdio: printf; immutable int n; shared static this() { n = 123; printf("n = %d\n", n); } shared static this() { n = 456; printf("n = %d\n", n); } void main() {} --- When run, the output is: --- n = 123 n = 456 --- Since it should not be possible to mutate an immutable variable after it has been initialized, the second static constructor is invalid, and should be rejected by the compiler. --
