Usually this http://www.microsoft.com/en-us/download/details.aspx?id=40336 should be used. gdb will for sure work not correct and many cases and is unusable for us. Also, if it's your build, don't forget to use --with-debug-pack or use debug build, that will give some better BT infos. Probably Dmitry is the one who should be looking at this :) Regards anatol
