在单声道下运行的 F# 编译器中的堆栈溢出



我正在更新我的项目 llvm-fs 的工具,所以我安装了新版本的 mono 并尝试编译它。在 OS X 下将mono 3.10.0fsharpc 3.1 一起使用,或在 ubuntu 下与fsharpc 3.0一起使用mono 3.2.8,编译失败并出现堆栈溢出:

Unhandled Exception:

您可以通过执行以下操作在 Linux 或 OS X 上重现此错误:

git clone git@github.com:fsprojects/llvm-fs.git
cd llvm-fs/
FSC=fsharpc ./build.bash

在窗口fsc 12.0.30815.0下,编译完成,没有错误:

fsc --nologo --debug --sig:LLVMFSharp.fsi --target:library --out:LLVMFSharp.dll src/LLVM/FFIUtil.fs src/LLVM/Generated.fs src/LLVM/Core.fs src/LLVM/BitReader.fs src/LLVM/ExecutionEngine.fs src/LLVM/Extra.fs src/LLVM/Target.fs src/LLVM/Quote.fs

这是一个已知问题,有什么方法可以解决它吗?我尝试将不同的选项传递给单声道运行时,但没有一个导致编译器正常退出。我确实记得过去单声道在尾声调用指令方面遇到了一些问题,但我认为这些问题大多得到了解决。谢谢!

这对于注释来说太长了,但是错误是由 generated .fs 中的这段代码触发的(因为注释掉它会停止堆栈溢出 - 一旦注释掉,稍后就会出现错误)(来自第 6496-6506 行):

 [<DllImport(
            llvmAssemblyName,
            EntryPoint="LLVMRunFunction",
            CallingConvention=CallingConvention.Cdecl,
            CharSet=CharSet.Ansi)>]
        extern void* (* LLVMGenericValueRef *) runFunctionNative(
            void* (* LLVMExecutionEngineRef *) EE,
            void* (* LLVMValueRef *) F,
            uint32 NumArgs,
            void* (* LLVMGenericValueRef* *) Args)
        // I don't know how to generate an "F# friendly" version of LLVMRunFunction

输出签名文件的代码中发生崩溃。

禁用签名文件可以解决问题(但某处仍然存在潜在的错误)。
