Package: libmarisa-perl Version: 0.2.5-3 Severity: grave Control: block 935737 with -1
As noticed by the autopkgtest checks, the marisa Perl bindings are totally broken in sid after the recent Perl 5.30 rebuild: $ perl -e 'use marisa' Can't load '/usr/lib/x86_64-linux-gnu/perl5/5.30/auto/marisa/marisa.so' for module marisa: /usr/lib/x86_64-linux-gnu/perl5/5.30/auto/marisa/marisa.so: undefined symbol: _ZTVN10__cxxabiv120__si_class_type_infoE at /usr/lib/x86_64-linux-gnu/perl/5.30/DynaLoader.pm line 193. at /usr/lib/x86_64-linux-gnu/perl5/5.30/marisa.pm line 11. Compilation failed in require at -e line 1. BEGIN failed--compilation aborted at -e line 1. Rebuilding marisa in testing with Perl 5.28 triggers the same behaviour, so it's not a change in Perl 5.30 that broke it. The previous sid build in July is not broken. It looks like this regressed with the gcc 8 -> 9 move. Linking the DSO manually with gcc-8 makes it go away, as seen below. I have no idea what goes wrong here, but I noticed that broken versions of blib/arch/auto/marisa/marisa.so have no NEEDED entry for libmarisa.so.0 (as seen with 'objdump -p'). ---- reproduce the error ---- # apt build-dep libmarisa-perl $ ./debian/rules build $ cd bindings/perl $ LD_LIBRARY_PATH=../../lib/marisa/.libs/ perl -I blib/arch -I blib/lib -e 'use marisa' Can't load 'blib/arch/auto/marisa/marisa.so' for module marisa: blib/arch/auto/marisa/marisa.so: undefined symbol: _ZTVN10__cxxabiv120__si_class_type_infoE at /usr/lib/x86_64-linux-gnu/perl/5.30/DynaLoader.pm line 193. at blib/lib/marisa.pm line 11.
