Ok, this was just a permission problem: cc1 was not allowed to read uvm_km.c.
I wonder why I didn't notice this earlier...

However, cc1 shouldn't fail.  Is anybody able to reproduce this (on current
or netbsd-5)?

$ cd /tmp && touch test.c
$ sudo chown 0:0 test.c
$ sudo chmod 600 test.c
$ gcc test.c
cc1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.

A tracing of the process shows:
