Can you elaborate? Are you talking about crashes unrelated to the alien-callstack problem? We (Qt Project) are happily shipping mingw-builds x32-4.8.0-release-posix-dwarf-rev2 as part of our SDK, without any problems (also from users). For Qt 5.3 we'll plan to ship i686-4.8.2-release-posix-dwarf-rt_v3-rev2... Previously we were shipping x32-4.7.2-release-posix-sjlj-rev8 , but got bug reports that compiled binaries were to slow (also compared to mingw.org). And the culprit was ... SJLJ, with about 25% penality for an application that essentially didn't use exceptions at all! See also http://comments.gmane.org/gmane.comp.gnu.mingw.w64.general/6874 It's of course up to everyone to decide whether the performance penality is worth the ability to throw exceptions to alien call stacks ... In the Qt world exceptions are traditionally used very conservatively.
