Initial Comment:
hi all, 
I'm using boost-1_33 with 
$ g++ --v 
Reading specs 
from /usr/lib/gcc/i586-mandrake-linux-gnu/3.4.3/specs 
Configured with: ../configure --prefix=/usr 
--libexecdir=/usr/lib --with-slibdir=/lib 
--mandir=/usr/share/man --infodir=/usr/share/info 
--enable-shared --enable-threads=posix 
--disable-checking --enable-long-long 
--enable-__cxa_atexit --enable-clocale=gnu 
--disable-libunwind-exceptions 
--enable-languages=c,c++,ada,f77,objc,java 
--host=i586-mandrake-linux-gnu --with-system-zlib 
Thread model: posix 
gcc version 3.4.3 (Mandrakelinux 10.2 3.4.3-7mdk) 
 
and, just compiled the first example from 
http://www.boost.org/doc/html/signals/tutorial.html#id1280117 
 I obtain a segmentation fault. 
 
this is the trace from gdb 
[max_at_macchese temp]$ gdb ./unitest

I compiled the source (in attach)  by: 
g++  main.cpp -o unitest  -I/usr/local/include 
-I/usr/local/include/boost-1_33/ -L/usr/local/lib 
-lboost_signals-gcc-d 
 
I tryied also libboost_signals-gcc-mt-d with the same 
result. 
hope this help
