Just tried it here:

NetBSD 6.99.3, i386, 4 cpu, wapbl enabled root

$ dumpfs / | grep wapbl
wapbl version 0x1       location 2      flags 0x0
wapbl loc0 7835392      loc1 16096      loc2 512        loc3 8
flags   wapbl 

No panic, no crash, only:

/dev/fss0: file system not clean (fs_clean=0x4); please fsck(8)
/dev/fss0: lost blocks 0 files 0

Should have mounted the snapshot read-only.
