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
