Question

我正在为我的项目llvm-fs更新工具，所以我安装了新版本的mono并尝试编译它。在OS X下使用mono 3.10.0 {1}}或在ubuntu下使用fsharpc 3.1 mono 3.2.8编译失败，堆栈溢出：

fsharpc 3.0

您可以通过执行以下操作在Linux或OS X上重现此错误：

在Windows git clone git@github.com:fsprojects/llvm-fs.git cd llvm-fs/ FSC=fsharpc ./build.bash下，编译完成且没有错误：

fsc 12.0.30815.0

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，没有一个导致编译器正常退出。我记得在过去单声道有一些关于尾部指令的问题，但我认为这些问题大多已经解决了。谢谢！

这对于注释来说太长了，但错误是由来自generated.fs的这段代码触发的（在其中注释掉它会停止堆栈溢出 - 一旦注释掉后会出现错误）（来自行6496-6506）：

 [<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

在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（但某处仍存在潜在的错误）。
