Seg fault in initdb

I just tried to run initdb with the latest CVS snapshot but initdb
segfaults, i.e. some programs inside do:

Vacuuming template1
Segmentation fault
Segmentation fault
Creating public pg_user view
Segmentation fault
Segmentation fault
Segmentation fault
Creating view pg_rules
Segmentation fault
Segmentation fault
Creating view pg_views
Segmentation fault
Segmentation fault
Creating view pg_tables
Segmentation fault
Segmentation fault
Creating view pg_indexes
Segmentation fault
Segmentation fault
Loading pg_description
Segmentation fault
Segmentation fault
Segmentation fault

Is this a known problem? Or do I have a local problem on my machine?
