We have finally found the problem - when we got our hands on a Mac that
showed it. It turns out that on some Macs (not others and no LInux
machines) the Z routine that reads the text files aborts when the first
line in the file is null (no blanks or anything). Other null lines
cause no problem - only the first. Unfortunately, the 2009 text file
had a null line at the start. It doesn't anymore. What causes the
abort is still a mystery - optimization level does not matter, but if we
run the task under the debugger it works.
Anyway, it should work for you now.
