Re: [Vala] Vala completion support for vim

[Damien Radtke <damienradtke gmail com>]

I believe I've found the problem. =)

I figured out how to enable debugging and discovered that the segfault
occurred in the CodeDom destructor. Part of the destructor runs a foreach
loop on "source_files", which was null. In order to make sure that object
creation worked correctly, my test included creating a CompletionEngine but
adding nothing to it; hence, a null list and the cause of the segfault. It
should be easily fixed by making sure that the list always exists, even if
it's empty.
