--- Comment #7 from boger at us dot ibm.com --- I've built with Dominik's patches against trunk on ppc64le and have been trying to run the gcc testsuite for go and libgo. The recover.go testcase continues to fail in my build. I did some debugging on this and found that the problem occurs in ffi_callback when it calls __go_makefunc_can_recover. Based on the comments I think it should be called with the program address for the most recent caller on the stack which is not ffi, but instead it is called with the address for ffi_closer_helper_LINUX64. I suspect this is happening because runtime_callers is not returning the complete set of callers. This error leads to an incorrect setting of __makefunc_can_recover in the __go_defer_stack structure so the test prints the "missing recover" error.
