Description marek 2000-08-02 15:34:50 UTC 
I'm not sure what kind of problem is this but when I run lsof with any 
parameter (except "-v" - version) it core dumps with the message "Illegal 
instruction". Here is a strace snippet :

getdents(4, /* 4 entries */, 984)       = 56
stat("/proc/1/fd/0", {st_mode=S_IFSOCK|0777, st_size=0, ...}) = 0
lstat("/proc/1/fd/0", {st_mode=S_IFLNK|0700, st_size=64, ...}) = 0
readlink("/proc/1/fd/0", "socket:[172]", 4095) = 12
--- SIGILL (Illegal instruction) ---
+++ killed by SIGILL +++

Upgrading to latest version (4.49) solved this.

I can also send in the core dump.

Probably caused by some hardware problems, will do some tests and report later.
