Bug#942073: marisa: perl bindings are broken when linked with gcc-9
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').
