As suggested by another user I tried with gcc 4.4.3 + boost 1.50 and it crash I have tried with boost 1.52 and it crash as well. At this point or is a boost bug (not yet resolved) or a gcc bug corrected by accident or not in the new release. GCC people do release fixes on old version then it's important to submit the bug as soon we know who is faulty here.
In my reply I pointed out that there is no way optional can legitimately cause this crash because it's not used with your class. The problem seems to be due to coincidence of several unknown factors in the code, only one of them being a mere presence and use of optional. Although it's not my position to say so, I do not think the author of Boost.Optional is willing to work around compiler bugs that are not directly caused by it. My advice: use a newer compiler. If that's not an option, try to work it around in your code. You've already presented several workarounds you found.
