Package: electric-fence Version: 2.1.16 Severity: important When I use electric-fence under gdb, the program being debugged segfaults during startup:

(gdb) set environment LD_PRELOAD /usr/lib/libefence.so (gdb) run Starting program: /bin/ls Electric Fence 2.1 Copyright (C) 1987-1998 Bruce Perens. During startup program terminated with signal SIGSEGV, Segmentation fault. (gdb) This is severity important because really one of the most useful cases for electric-fence is running under gdb. I believe it may have something to do with libc6 2.13, since it has worked very recently and the breakage seems to coincide with the upgrade. Nevertheless, it appears unrelated to the memcpy issue, since it breaks on amd64 machines both with and without ssse3. If you need me to test or provide more information, please let me know. -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 2.6.39-rc5-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages electric-fence depends on: ii libc6 2.13-2 Embedded GNU C Library: Shared lib electric-fence recommends no packages. electric-fence suggests no packages. -- no debconf information -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | http://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: RSA v4 4096b: 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187
