There is, at least, a zero divide error :

[...]
      build  libsyspuffs/librumpfs_syspuffs_pic.a
/local/src/NetBSD/tool/bin/nbawk: floating point exception: Floating point 
divide by zero
 input record number 435, file
 source line number 1
    compile  libsyspuffs/puffs_rumpglue.o
      build  libsyspuffs/librumpfs_syspuffs.so.0.0
      build  libsyspuffs/librumpfs_syspuffs.a
/local/src/NetBSD/tool/bin/nbawk: floating point exception: Floating point 
divide by zero
 input record number 435, file
 source line number 1
    compile  liblfs/lfs_vfsops.po
[...]
