Anybody interested in this or could point me to a different boost list?

Hello,
I figured that shared_ptr (boost 3.4, but I don't think this is really a boost problem) will lose memory in the following example ... int main(int argc, char** argv) { while (true) { XRef myX; try { myX = getx(); } catch(...) { } } } ... Platform is FreeBSD 6, gcc 3.4.6. It only happens when compiled like above (without optimization).
I'm interested in principle in everything concerning shared_ptr, but I'm not sure what we can do about this specific case. Maybe report it to the GCC Bugzilla? Is 3.4.6 even being maintained? Thanks for your response.
I'm not certain if 3.4.6 is still maintained (the gcc site is not very specific about this), but since it is still shipped with some OSes as default I thought it might me worthwhile to put a warning somewhere in the boost documentation (sth like "known issues") to save somebody else from getting hit by this (in my case it was a server process crashing once a week for no apparent reason). Posting a bug at the gcc mailing list would only be an option if I can track this further down so I can report it without referring to boost (otherwise I'm pretty sure they will tell me to report this to the boost mailing list :). I don't know shared_ptr's internals (yet) and if this relates to something that is very specific to shared_ptr or a general issue that is easy to put in a small example case. So if you or anybody has a clue what might cause this I could try to get this to the gcc guys. If not, I would just suggest a warning in the documentation and hope that 3.4 won't be used by anybody in the near future. /michael
