These objects file are not created from the makefile. It sounds more like it's running into some kind of resource limit.
tmpfs maybe? Just wondering since i got that exact error when building wine on OBS.. Also got a couple of other very strange errors that failed building on OBS with files that was not found, but could not find a error message from the actual compile..
