Nim中返回值为void的lambda致编译器崩溃，是否需提交反馈？

出错的最小复现代码 #

import sugar

type TestLambda = () -> void
type NamedTestLambda = tuple[name: string, lambda: TestLambda]

var testNil: TestLambda = () => void

var funcs: seq[NamedTestLambda] = @[
    (name: "nil", lambda: testNil),
]

编译时触发的内部错误 #

Error: internal error: getTypeDescAux(tyVoid)
No stack traceback available
To create a stacktrace, rerun compilation with './koch temp c <file>', see https://nim-lang.github.io/Nim/intern.html#debugging-the-compiler for details
     Error: Build failed for package: nim_snake
        ... Execution failed with exit code 256

可正常编译的对比代码 #

将lambda返回类型改为int后，代码可正常编译：

import sugar

type TestLambda = () -> int
type NamedTestLambda = tuple[name: string, lambda: TestLambda]

var testNil: TestLambda = () => 1

var funcs: seq[NamedTestLambda] = @[
    (name: "nil", lambda: testNil),
]

结论 #

这不是你的代码问题，是Nim编译器1.6.16版本的内部错误，应该向Nim官方提交问题反馈。
