It just so happens that I have a backtrace-on-assertion-failure patch in my tree: [...] dpkg-source: info: extracting mig in mig-1.4 dpkg-source: info: unpacking mig_1.4.orig.tar.bz2 ext2fs/ext2fs_t: ../include/refcount.h:159: refcounts_ref: Assertion `! (r.hard == 1 && r.weak == 0) || !"refcount detected use-after-free!"' failed. /home/teythoon/build/hurd-upstream/lib/libdiskfs.so.0.3(diskfs_S_dir_lookup+0x389)[0x1093869] /home/teythoon/build/hurd-upstream/lib/libdiskfs.so.0.3(+0x10636)[0x1099636] /home/teythoon/build/hurd-upstream/lib/libdiskfs.so.0.3(diskfs_demuxer+0x97)[0x1092a87] /home/teythoon/build/hurd-upstream/lib/libports.so.0.3(+0x39ae)[0x10e69ae] /lib/i386-gnu/libc.so.0.3(mach_msg_server_timeout+0xb6)[0x111f886] /home/teythoon/build/hurd-upstream/lib/libports.so.0.3(+0x3b2e)[0x10e6b2e] /lib/i386-gnu/libpthread.so.0.3(+0x4b06)[0x104db06] tar: mig-1.4/build-aux: Cannot utime: Computer bought the farm tar: mig-1.4/INSTALL: Cannot open: Computer bought the farm tar: mig-1.4/AUTHORS: Cannot open: Computer bought the farm [...] This is just a stupid demo of course, I put that refcount bug in there. I'll put that patch in my package and you can give it a try on darnassus. Justus
