For the records, the test case at line 10 was:

        printf _("%s\n"), "$a";

It was parsed alright in xgettext 0.14.5.  Version 0.15.0 produces the 
error here.  Can you double-check the changes between 0.14.5 and 0.15 to 
the Perl parser backend? It looks like something has been broken along 
the way between 0.14.5 and 0.15.

I tested with the two versions compiled by the Gentoo tools on my 
system, but I would be very surprised, if the behavior was not 
reproducable with the vanilla sources.

Regards, Guido

P.S.: BTW, using a single underscore as the function alias for gettext 
in Perl is often a bad idea, since functions whose names consist of a 
single interpunction character are automatically global in Perl, i.e. 
the function is visible in all namespaces, and can be re-defined in all 
namespaces.
