I'm a gentoo user, and just recently installed clucene in prep for beginning to use it with my new dovecot server.
On installation of the stable package dev-cpp/clucene-184.108.40.206-r1, I get the following post-install warning:
QA Notice: Package triggers severe warnings which indicate that it
may exhibit random runtime failures.
/var/tmp/portage/dev-cpp/clucene-220.127.116.11-r1/work/clucene-core-18.104.22.168/src/core/CLucene/index/DocumentsWriter.cpp:129:33: warning: passing NULL to non-pointer argument 2 of ‘void* memset(void*, int, size_t)’
Please do not file a Gentoo bug and instead report the above QA
issues directly to the upstream developers of this software.
So, here I am, reporting the bug upstream as requested by the gentoo devs...
