I confirmed that it does in fact have to do with the partition layout. I
originally had hda1,2,3.4 - hda1 was a Windows partition, hda2 and 3
linux, and hda4 swap. I removed hda1 (not like I use Windows anymore
anyway...) and recompiled util-linux (by the book - default compiler
settings). It segfaulted again. Then I removed hda4 and recompiled again
- it worked fine.
