I have been running aide. Worked okay for some time, but started segfaulting a few days ago. <snip> GNU gdb 6.3 [..] (gdb) run -u Starting program: /usr/bin/aide -u (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) Program received signal SIGSEGV, Segmentation fault. 0xb7e0d6fb in strlen () from /lib/tls/libc.so.6 (gdb) bt #0 0xb7e0d6fb in strlen () from /lib/tls/libc.so.6 #1 0xb7de24e3 in vfprintf () from /lib/tls/libc.so.6 #2 0xb7de3f64 in vfprintf () from /lib/tls/libc.so.6 #3 0xb7ddff62 in vfprintf () from /lib/tls/libc.so.6 #4 0x0804c180 in error () #5 0x0804a40a in ??

Any ideas?
doubtful, util-linux has no libraries, just programs the back trace you provided is worthless, please run: FEATURES=nostrip CFLAGS='-g -O2 -pipe' emerge aide and then run it through gdb again

Ahh! Got it. The error is in confparse. Looking at my config file: it has an error in it. Segfaulting upon that is not nice, but anyway... Closing as invalid. Sorry for bothering.
