The OOCalc formula function CURRENT() does work when it is used as an argument
for another function, but not when that function is itself an argument for a
third function.

For example, the following two formulae produce exactly the same output, as one
should expect (with B1 holding a number, and A1:A5 a list of five numbers sorted
in ascending order):

=      MATCH( B1;        A1:A5 )
= B1 + MATCH( CURRENT(); A1:A5 ) - B1

Similarly, one should also expect the following two formulae to produce the same
output as each other:

=      INDEX( A1:A5; MATCH( B1;        A1:A5 ))
= B1 + INDEX( A1:A5; MATCH( CURRENT(); A1:A5 )) - B1

However, while the first one returns the proper value from the list A1:A5, the
second one causes a #VALUE! error.

The simple example given is of course rather useless, but I do have a
spreadsheet where I would like to set conditional STYLE() values depending on
rather complex value lookups based on the CURRENT() cell value, which this bug
seems to unfortunately make impossible.
