Using gdb I get the following seg fault. I also included a backtrace.

If I compile the attached file with a version of trunk current as of a few days ago it works fine on 32 bit Linux but produces a seg fault on 64 bit Linux. An older version of 1.34+ from a few months ago works fine.
I configured using:
./configure --prefix=$HOME/boost_test --without-libraries=python,serialization,graph,test
Thanks for reporting it. I have no access to a 64 bit machine right noow but I'll try to get it ASAP. The example seems simple. I think you've already tested it, but are you sure it's a segfault and not an exception being thrown? If so, could you launch it with the debugger to see where the error is notified? Regards,
