Not sure how to file this bug

In the past few weeks, I am not sure exactly when, clamav (www.clamav.net) has ceased to work. I have tried their cvs and new versions... nothing works. It dies with a SIGILL. # freshclam ClamAV update process started at Mon Mar 15 22:17:21 2004 Reading CVD header (main.cvd): OK main.cvd is up to date (version: 21, sigs: 20094, f-level: 1, builder: tkojm) Reading CVD header (daily.cvd): OK Downloading daily.cvd [*] Illegal instruction This seems to me to be either a change in glibc, gnuc et al, or the kernel. Has a non-executable stack patch been added lately? Does it throw a SIGILL instead of a SIGSEGV? I am running a recent Athlon (2200+). According to cpuinfo it supports cmov, so I don't think that is it. processor : 0 vendor_id : AuthenticAMD cpu family : 6 model : 8 model name : AMD Athlon(tm) XP 2200+ stepping : 0 cpu MHz : 1797.047 cache size : 256 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 mmx fxsr sse syscall mmxext 3dnowext 3dnow bogomips : 3555.32 I am running the latest development as of this morning (including kernel-2.6.3-2.1.253). I know devel/rawhide can be treacherous, but if no one tries it, bugs don't get found and fixed. So, how do I go about filing this bug?
