Can you please try compiling without -fomit-frame-pointer? gcc 3.3.x had some problems with -march/-mcpu=k6-2 and -fomit-frame-pointer. As a side note, you should consider upgrading your gcc to 3.4.x.
(In reply to comment #1) > Can you please try compiling without -fomit-frame-pointer? gcc 3.3.x had some > problems with -march/-mcpu=k6-2 and -fomit-frame-pointer. thanks for the fast reply. omitting -fomit-frame-pointer did not help, same behavior. After this i reemerged 0.88, and sh.. this also does not work anymore. Same behavior ( seg fault ). I checked thermal condition of CPU, no problem. Would it be helpful for you to see a list of packages which where emerged after i first emerged 0.88 which was working? > > As a side note, you should consider upgrading your gcc to 3.4.x. >
Yes, the list can't hurt. Also, have a look at bug #129702, although I don't think this is related. It would probably be worth it trying to get a gdb backtrace (when compiled without --fomit-frame-pointer) and reporting it to clamav-user mailinglist.
Created attachment 84614 [details] files emerged after working 0.88 here is the list.
tried to get a backtrace, but it seems this is not very usefull. Am i missing something. emerged gdb changed CFLAGS to -mcpu=k6-2 -pipe -ggdb3 added nostrip to FEATURES reemerged clamav 0.88.1 fatboy ~ # gdb freshclam GNU gdb 6.4 Copyright 2005 Free Software Foundation, Inc.

clamav-0.88.2 is in portage now, does that one work for you?
This was no bug in clamav! I rebuild the toolchain and then the complete system. Now it works.
