test-nfkc fails if poppler was built with -Bsymbolic: AssertionError: Regexp didn't match: '^\xef\xac\x82uorogra\xef\xac\x81a *$' not found in 'fluorografia \n\x0c\x0c' #90

What steps will reproduce the problem?
1. Install Poppler 0.24.x
2. Try to build the Debian package

What is the expected output? What do you see instead?
One of the tests fails:

FAIL: test-nfkc.test.test_no_nfkc
----------------------------------------------------------------------

This does not happen with Poppler 0.22.

Thanks for the bug report.

0.24.x for what value of x exactly?

I'm asking because IIRC I tested pdf2djvu against poppler 0.25.0, 0.24.3 and 
probably also 0.24.4, and didn't notice any test failures.

I tested with 0.24.3 (apt-pinned from Ubuntu trusty on Debian).

My wild guess is that poppler built with -Bsymbolic-functions breaks the test.
(Although I don't quite understand why it started failing only now; it should 
fail for any poppler ≥ 0.19).

I will investigate this later.

I've reproduce the test failure in the setup you described.

As I suspected, if you rebuild poppler_0.24.3-0ubuntu8 in Debian environment, 
the failure is no longer reproducible.

Ok, thanks for the investigation. This is still a (minor) bug, though.
