We will be shipping a large game in a couple weeks on android that is built on gnustep. We've been testing very extensively over the past 3-4 months and things look quite stable (at least on armv7-a). The game heavily uses ARC, blocks, libdispatch.... Lemme just say the configuration of gnustep-base, build, and project setup, were........ not ideal.
