 Quick re-test with early results:
 
 * 11.0_RC1 - last known to crash
 
 * 11.0_RC2 to RC4 - unable to find ISO to download and test
 
 * 11.0_RC5 - does not crash
 * 11.0_RC6 - does not crash
 * HEAD - 20260720014948Z - does not crash
 
 Tested commands (should crash in few seconds if vulnerable):
 
 fssconfig -cx fss0 / /root/backup
 dd if=/dev/fss0 of=/dev/null bs=1024k
