(The relative order of declarations remains the same; Just grouped the coupled declarations) This changed test passes with -fno-pic and fails with -fpic. BUT if we comment out the first group of definition/declarations the test will fail with -fno-pic with the same problem, eventhough those two groups are completely independent of each other test case is attached in the previous comment ^ permalink raw reply [flat|nested] 5+ messages in thread
