#852 img-reorder hangs on large data: URI images

[Incognito]

img-reorder filter hangs (or takes a very long time (core at 100%)) on pages with large in-line data: URI images using data: URI scheme.
Example: http://dopiaza.org/tools/datauri/data-uri-examples/
Tested on 3.0.19 on Windows 7 64bit.

Upon further testing, banners-by-size has similar problems with large enough images.

Easy solution would be to put some reasonable limits on the match size in the regexps.

Thanks for the report.

It looks like more recent PCRE versions already "solve" this with the internal match limit:
14:53:42.869 029 Error: Skipped filter 'privoxy-filter-test' after job number 5: (pcre:) Match limit reached (-8)

Unfortunately we can't rely on a more recent PCRE version being available, so I'll look into this.
