And whether that's target specific? The test doesn't fail with gcc-5 but I haven't computed the actual increase from 5 to 6. Although the hppa-linux target has the same frame allocation as 32-bit hpux, I think make bumps the default stack allocation up on linux. So, there is a difference when test is run using make on linux. The 64-bit hpux target has a 16-byte minimum frame allocation. That's probably why it doesn't fail there. Dave
