#222 Crash looking for vamp plugins

Mercurial tip

Problem exists on mercurial tip, but also seen with default Ubuntu 16.04 package installation. Trying to launch sv cores when looking for plugins. I currently have vamp-plugin-sdk v2.5, also does it with vamp-plugin-sdk tip.

    Apparently this is indeed a problem of the plugin, however it seems that sv should be able to catch the exception.

    Do you happen to know which plugin is causing this?

    If you're building from hg, then perhaps try the 3.0-integration branch. This contains some work targeted for the next major release, including a separate process which is used on startup to scan for plugins and eliminate any that crash on instantiation. However, it may be ever more fiddly to build and run than the default branch is!

    I think this was a compilation issue with gcc v4/5. I did encounter this with all prebuilt packages though. It ended up being vamp-aubio that was the particular culprit.
