Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

Relevant part (hopefully):
> make[1]: Entering directory '/<<PKGBUILDDIR>>/doc'
> perl texi2html -split_chapter -no_toc_href fftw.texi
> Unescaped left brace in regex is deprecated here (and will be fatal in Perl 5.30), passed through in regex; marked by <-- HERE in m/\@(\w+){ <-- HERE ([^\{\}]+)}/ at texi2html line 1771.
> Unescaped left brace in regex is illegal here in regex; marked by <-- HERE in m/\@value{ <-- HERE ([^\s\{\}]+)}/ at texi2html line 842, <FH001> line 4.
> Makefile:799: recipe for target 'html' failed
> make[1]: *** [html] Error 25

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
