Could you try to reproduce the issue with the version you hit it
earlier? It'd be helpful to get a backtrace.

Did you have any modifications in the tree?

Did you do a build, pulled some updates, and built again? I noticed
that you didn't pass --enable-depend to ./configure, so it's possible
that not all files got rebuilt that needed to.
