Do you have DIAGNOSTIC in your config file?

If you did, perhaps you would have gotten this crash instead, which
I get when making in distrib/i386/floppies/ramdisk-tiny:

	"panic: kernel diagnostic assertion "bytes != 0" failed: file 
	miscfs/genfs/genfs_vnops.c line 963

This is repeatable, and I have a core dump, but no netbsd.gdb file.
