Lines 373 onwards of licensecheck loops through potential copyright
lines.  Line 377 does another loop within that, merging with next
potential copyright line if the line ends in digit (and maybe more).

That inner loop fails and loops endlessly if there are no more lines to
merge from.

A fix is to skip inner loop if on last line - i.e. change from this:

	    while ($copyright_match =~ /\d[,.]?\s*$/) {

to this:

	    while ( (@c) and $copyright_match =~ /\d[,.]?\s*$/ ) {


Current devscripts package causes ghostscript, and possibly other
packages, to FTBFS, thus raising to severity important.
