Description KaptOc6obnuCac0Bluc+bugzilla.xamarin.com 2015-01-23 09:58:32 UTC
When I tried to `mono --llvm --aot=full FsCheck.dll` it crashes with Mono Ahead of Time compiler - compiling assembly /tmp/FsCheck.dll mono: Instructions.cpp:281: void llvm::CallInst::init(llvm::Value *, ArrayRef<llvm::Value *>, const llvm::Twine &): Assertion `(i >= FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling a function with a bad signature!"' failed. The dll and the stacktrace are attached.

Comment 3 Zoltan Varga 2015-01-23 19:52:56 UTC
Please attach the FsCheck.dll dependencies as well. Also note that --aot=full is intented for use on environments which don't allow JITting, it doesn't make too much sense on amd64.
Comment 4 KaptOc6obnuCac0Bluc+bugzilla.xamarin.com 2015-01-23 20:11:32 UTC
Created attachment 9482 [details] F# Core (dependency) FSharp.Core.dll is attached. This is the only known dependency for FsCheck. FsCheck are also available in binary form: https://www.nuget.org/packages/FsCheck/ FsCheck are also available in source form: https://github.com/fsharp/FsCheck
Comment 5 Zoltan Varga 2015-01-24 19:11:29 UTC
Fixed in mono master f342649f75bf13da8c1e14342a2dd69655add6e0.
Comment 7 Zoltan Varga 2015-02-19 11:01:03 UTC
The issue only happens with a 64 bit mono runtime, and we don't distribute that right now, so its kinda hard to reproduce without compiling one. I'd suggest treating this as verified.
Comment 8 KaptOc6obnuCac0Bluc+bugzilla.xamarin.com 2015-02-19 12:55:52 UTC
Well, the distribution about the 64bit mono runtime is more or less true - it would be good to have 64 bit runtime on 64 bit cpu. Please note community builds are already available to everyone (it also support most linux distribution), and also listed on the Mono Project homepage. Steps to reproduce on Ubuntu 14.04 x86_64: 1) Add tpokorra repo to your distribution, which is also available on Mono Project download page: http://www.mono-project.com/download/#download-lin "Community packages" "Mono Packages installed to /opt for CentOS, Fedora, Debian and Ubuntu" 2) Download Fsharp.Core.dll (if you don't have F# already installed) and FsCheck.dll from the issue. 3) Execute the following command: source /opt/mono/env.sh mono --llvm --aot=full FsCheck.dll
