 Hello.
 uwe at netbsd prodded that i dig a bit deeper and so here is the
 thing a bit narrowed down.  Sorry.
 
  | Please, can you minimize the test case?  As far as I understand it
  | should be reducible to the script and to a single line of input that

 Hmmm.
 
   cat > test.sh <<\!
   printf '1 '; printf "F0000\n" |
   awk '{r2 = r1 = sprintf("%d", "0x" $1); while (r1 <= r2) {print r1; ++r1}}'
   printf '2 '; printf "F0000\n" |
   awk '{r1 = sprintf("%d", "0x" $1); r2 = r1; while (r1 <= r2) {print r1; ++r1}}'
   printf '3 '; printf "F0000\n" |
   awk '{r1 = sprintf("%d", "0x" $1); while (r1 <= 983040) {print r1; ++r1}}'
   printf '4 '; printf "F0000\n" |
   awk '{r1 = sprintf("%d", "0x" $1); r2 = sprintf("%d", "0x" $1); while (r1 <= r2) {print r1; ++r1}}'
   printf '5 '; printf "F0000\n" |
   awk '{r1 = sprintf("%d", "0x" $1); r2 = sprintf("%d", "0x" $1); while (r1 <= r2) {print r1; ++r1}}'
   printf '6 '; printf "F0000 F0001\n" |
   awk '{r1 = sprintf("%d", "0x" $1); r2 = sprintf("%d", "0x" $1); while (r1 < r2) {print r1; ++r1}}'
   sh ./test.sh
 
 results in
 
   1 983040
   2 983040
   3 983040
   4 983040
   5 983040
   6
 
 So -- indeed.  Sorry.

 But
 
   $ make ucd; ll test/sa/t_props.dat; make ucd-clean;\
   sed -e 40d -i '' tools/t-base.t; make ucd; ll test/sa/t_props.dat
 
 becomes (when i strip all the other messages)
 
   ucd: ok

   ucd-clean: ok
   ...
   ucd: ok
