--- Comment #8 from Gaetano Mendola <mendola at gmail dot com> 2012-11-24 12:25:35 UTC --- Jonathan, I have nothing against you personaly, what you wrote is: "GCC 4.4 is no longer supported, and the problem *seems* to be already fixed in current releases." and doesn't exactly show that you have investigate, I have also stated that with 4.7.3 works. Actualy the code I have submitted was tailored already I couldn't shrink more than I did. To be honest with the real code instead to have a "pure virtual call" I had a simple core with gdb finding bogus data in the core, that was the smallest test I was able to make it reproducible. About the fact I didn't post the g++ -v output you are right, I have issued the command "g++ -v -save-temps ..." but somehow the output get lost in the archive attached. If you are interested in the output I will provide it. About the fact to pay you to find the patch/commit correcting it just send me a commercial proposal to my email address. Thank you for your time. Regards Gaetano Mendola
