I already had to re-emerge dev-libs/libuv to build the debug version.
No change in behavior.

This is from a completely fresh install using the very recent

I am getting a segmentation violation when running a recompiled
'cmake'. I rebuilt with debugging symbols; here are the results:

Who can I work with to debug this?
