SIGSEGV on compile

[nicholasbarger]

This is my first time looking into buildpack's for heroku, but I've got a .NET Mono app attempting to compile and fails with the following log (below). Is there anyway to tell which library is failing or if it is a nugget issue first that is causing the library to fail (as a dependency)?

used by your application.

Well, I've done a couple things so far... I moved the heroku repo and associated heroku web role to just the MVC web app and not at the root where I had a SLN file and several class libraries as well. I committed nuget.exe into the root of the directory and began removing any potentially unused packages.

I get a new message which looks a bit further along, but still error out:

sorry - I'm not really working on this buildpack at the moment, if anything I'm focusing on the new ASP.NET 5 stuff

Bummer. I thought this was very exciting and brought more .NET developers further into more diverse cloud offerings and polyglot architectural decisions. Do you know if any of the other original contributors will be working on this since it's listed as the unofficial-official third party buildpack? https://devcenter.heroku.com/articles/third-party-buildpacks
