There seems to be a binary compatibility problem: signatures.pm is currently very broken, but just recompiling the package against current sid fixes it. % cat s.pl #!/usr/bin/perl -w use signatures; sub foo($x) {} % perl s.pl zsh: segmentation fault (core dumped) perl s.pl % sudo dpkg -i tmp/libsignatures-perl_0.12-1+b1_amd64.deb (Reading database ... 268292 files and directories currently installed.)

So apparently signatures needs the same version of B::Hooks::Parser at runtime as at compile time. This is clearly due to https://github.com/karenetheridge/B-Hooks-Parser/commit/3a9c69e71bb5b0d0d2489a32a29509195577d157 https://github.com/karenetheridge/B-Hooks-Parser/commit/d62e1b58535d64d59f044397550ebe1f4eee1765 which changed the parameters of hook_parser_setup(), breaking the ABI. The API still stays the same, so a recompile is enough. Fortunately this seems like a one time thing, and libsignatures-perl is the only reverse dependency of libb-hooks-parser-perl, so we can probably manage with something like - upload libsignatures-perl 0.13 with a build + runtime dependency on libb-hooks-parser-perl (>= 0.16) - upload libb-hooks-parser-perl 0.16-2 with a Breaks: libsignatures-perl (<< 0.13) -- Niko Tyni [email protected]
