I have reported the following Debian bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812318
With Subversion 1.9.3: $ perl -MSVN::Core -e 'SVN::Core::dirent_canonicalize(undef)' zsh: segmentation fault (core dumped) perl -MSVN::Core -e 'SVN::Core::dirent_canonicalize(undef)' In case of undef, I suppose that the Perl module should pass the empty string to the library (for which there are no errors), or return some other kind of error. I have not tried other kinds of arguments, but in any case, the module should make sure that a valid string is passed to the library. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
