Subject: I'm getting a currupted freelist

When I'm compiling, I have been getting problems with a corrupted freelist.
I'm running current as of 040894, and after a while cc1 gets a funny
signal (either 4 or 11, it varies). The kernel prints out something like
this:
Aug 2 04:57:05 foobar /netbsd: Data modified on freelist: word 0 of object
0x503800 size 72 previous type exec (0xeadbeef != 0xdeadbeef)
Aug 2 06:34:07 foobar /netbsd: Data modified on freelist: word 0 of object
0x4b8400 size 24 previous type VM pvmap (0xeadbeef != 0xdeadbeef)
Aug 2 06:34:18 foobar /netbsd: Data modified on freelist: word 0 of object
0x503480 size 24 previous type VM pvmap (0xeadbeef != 0xdeadbeef)
After this happens, I can't exec anything. Whenever I try, it gets a
segmentation fault and core dumps.
I'm running a custom kernel on a 2500 (A2630+A2091). If any one wants, I
can provide my kernel config file. I removed everything I don't need;
the only SCSI controller is for the 2091, no Retina code, no ethernet
adapter, no NFS server or client, and no ISOFS. I also left the kernel
debugger out.
Any ideas?
