Thank you for highlighting this failure.
it appears to be due to a bug in their version of tr.
Here's a snippet from your log:

+ tr -cs 0-9 '[ *]'
+ LC_ALL=C env -- tr -cs 0-9 '[ *]'
+ LC_ALL=cs_CZ.UTF-8 grep -F -f cspatfile csinput
+ echo ]11]12]13]14]15]16]17]18]
+ test1=]11]12]13]14]15]16]17]18]
+ test ]11]12]13]14]15]16]17]18] '!=' '11 12 13 14 15 16 17 18'
+ echo 'Test #1 F failed: ]11]12]13]14]15]16]17]18]'
Test #1 F failed: ]11]12]13]14]15]16]17]18]

That corresponds to this code:

test1=$(echo $(LC_ALL=$cz grep -${mode} -f cspatfile csinput |
               tr -cs '0-9' '[ *]'))
if test "$test1" != "11 12 13 14 15 16 17 18"; then
  echo "Test #1 ${mode} failed: $test1"
  failures=1
fi

and the value of $test1 somehow has a "]" in each position where
normally we'd expect a space.
That suggests the tr filter malfunctioned.

This failure does not block the release.
