"InterlockedCompareExchange@12" not be found in DLL "libstdc++6.dll"

Hey,
I use Qt5.1.0 with mingw48_32 on Windows 7 64bit. For some reason I had to add another compiler version. I downloaded Mingw 32 bit with gcc 4.7.2 and added it as custom compiler to Qt Creator.
I configured it as follows:name: MinGW4.7
path to compiler: C:\MinGW\bin\g++.exe
path to make: C:\MinGW\bin\mingw32-make.exe
ABI: x86-windows-msys-pe-32bit
header path: C:\MinGW\include
Then I created a custom Kit which makes use of the custom compiler.
When I compile my project with this kit, and later click on the generated .exe file, I receive an error similar to this (translated from German):
"InterlockedCompareExchange@12" could not be found in DLL "libstdc++6.dll"
What might this be? And how can I solve it? Did I add the custom compiler wrongly?

Hi,
AFAIK, you can't mix libraries built with MinGW 4.7 and MinGW 4.8

Yes, that was my guess, too. So is there a way to have Qt with MinGW 4.7 other than recompile Qt?
For now I simply replaced the incompatible 4.7-.dlls with the 4.8 counterparts, namely libgomp-1.dll and libstdc++6.dll. I hope, no further problems occur...
Thanks for the response!

AFAIK, no, you'll need to rebuild Qt
