Folks-

Weird issue I've come across in the past few days. It seems the behavior of FILE_LINES has changed from 8.4 to 8.5.

I've used a line of code like this since pre-7 days with no problems:

nLines = FILE_LINES(f, /COMPRESS)

where f is a basic gzipped file.

Now, this returns zero for me.

Anyone else using FILE_LINES with compressed files?

Here's a concrete example:

IDL> f='LYLOUT_120522_030000_3600.dat.gz'

(File available here: https://goo.gl/ROaE3J)

Under 8.4, I get:
IDL> file_lines(f, /compress)
123806

but under 8.5 I get:
IDL> file_lines(f, /compress)
0

The file really is gzipped:
$ file LYLOUT_120522_030000_3600.dat.gz
LYLOUT_120522_030000_3600.dat.gz: gzip compressed data, was "LYLOUT_120522_030000_3600.dat", from Unix, last modified: Sat Jul 7 08:30:46 2012, max compression

Running on Mac 10.9.5 FWIW.
