Running `updatedb` causes a segmentation fault on my hardened gentoo system. The crash happens within libc, namely during the call of "fts_read(dir)" (main.c - only one occurence). In my case the surrounding loop is executed multiple times without any problems (exactly 14409 times). The 14410th execution of the loop makes fts_read() segfault. The argument "dir" does not look suspicious although I have not inspected it in all details.

The problem was caused by a file system issue. It does no longer occur after the problem has been fixed. Hence, I closed the bug.
