--- Comment #12 from Erik van Pienbroek <erik-gcc-bugzilla at vanpienbroek dot nl> --- (In reply to tim.lebedkov from comment #11) > Qt 5.2.1 cannot be build in 32 bit with mingw-w64 4.8.2 because of this bug. > Why is it not fixed? A fix for this issue was applied in the intrin.h of mingw-w64 v3.1.0 (which was released in January 2014). Here's the commit in question: http://sourceforge.net/p/mingw-w64/code/6303/ You might want to consider updating your toolchain. I can't judge whether the fix applied in mingw-w64 is correct or whether something needs to be changed in gcc itself as well. Therefore I'm leaving this bug open for now. If the gcc devs think otherwise feel free to close this bug. Qt5 itself can now be built properly against gcc 4.8.2 and mingw-w64 v3.1.0 without any issues.
