This is a "segmentation violation". It means the program is trying to
access memory that it never allocated (i.e., it's trying to access memory
belonging to another process). This generally happens in 1 of 3 cases:
1) The program is a virus, etc trying to steal data from other programs.
2) The program was written poorly and has memory management bugs.
3) Your hardware (RAM) is buggy and memory bits are flipping by accident
causing unpredictable memory access.

This is a more unusual error, but still related to memory:
This error is more difficult to create using software than a segfault.
My theory at this point is that you either
a) downloaded precompiled packages that are not supported by your
b) built these from ports with funky CFLAGS settings
My recommendation would be to start out by deinstalling clam, and rebuilding
it from ports, ensuring that your /etc/make.conf settings are all set to
If the problem persists, install a program like memtest86, or use some
other RAM tester to ensure that your hardware is solid.
