[Boost-users] boost, LD_PRELOAD and segfault

Hi all,

   I'm experiencing something very weird. I'm developing a shared object
   written in C++ and linked against libboost-serialization-gcc41.so. This
   dynamic library is preloaded before launching a test program (proftpd).

   As soon as a try to log into the ftp server using a non-anonymous user, I
   get a segfault from the child the was handling the client connection. Of
   course, the same code, without libboost-serialization-gcc41.so linked
   against is perfectly working.

   I also removed any serialize method so basically only the libboost header 
   file are included with the library linked as well.

   Do you guys have any idea of what's going on?

   Libboost version 1.34.1, gcc version 4.1. I'm going to build the gcc-3.4
   version of the library and I'll turn debugging on.

TIA, bye
Lorenzo

PS: of course I tried to debug but what I got was pretty useless. No clue.
For instance, strace showed a syscall (gettimeofday) is successfully invoked 
before the segfault.
