Hi, i can't repeat this bug.. I suspect it can be caused by errors in debian/rules, since in current version of stx-btree i use `dh_prep` from both `install-arch` and `install-indep` targets, can they interfere on multicore box ? Maybe i should make some pre-install target and do all this stuff (dh_testdir.... dh_installdirs) from it ? Cheers Yury
