Compiled-in qrc files handled differently on Windows and Linux

I use 2 ressource files in a project with qml files. I have a base.qrc some qml files and an override.qrc with just a few files modified, that are also present in base.qrc.

When i use RESOURCES += override.qrc base.qrc
on Linux the modified files from override.qrc are used, but on Windows the base.qrc files are used.

When i use RESOURCES += base.qrc override.qrc
on Linux the files from base.qrc are used, but on Windows the files from override.qrc are used.

So Linux uses the first file found but Windows the last file found in the resources.

Same results when using a CMake based project.
Shouldn't this be handled equally across different platforms?
 
edit: fixed RESOURCE typo
