hi,

here's the problem: several commands i try to run in debian unstable
gives me a segmentation fault. some of them are nmap, eterm and php4.

evem when i download and build from source the result is the same.
version are:

php4 4.3.2+rc3-6
nmap 3.45-1


as an example, heres an ldd /usr/bin/nmap:

yamagata:~# ldd /usr/bin/nmap
libpcre.so.3 => /usr/lib/libpcre.so.3 (0x40020000)
libssl.so.0.9.7 => /usr/lib/i686/cmov/libssl.so.0.9.7
(0x4002e000)
libcrypto.so.0.9.7 => /usr/lib/i686/cmov/libcrypto.so.0.9.7
(0x4005d000)
libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x4014e000)
libm.so.6 => /lib/libm.so.6 (0x40206000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x40228000)
libc.so.6 => /lib/libc.so.6 (0x40230000)
libdl.so.2 => /lib/libdl.so.2 (0x4035e000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

and an strace nmap gives:

any idea why this is happening ? i have pretty much the same setup in
my personal box at home and it works nicelly. the problematic box here
at the office is:

CPU: Duron 1.4 GHz
RAM: 256MB
Video: SiS onboard (see a copy of lspci below)
