I see that stdlib.h include was removed by r231697 | edlinger | 2015-12-16 15:24:52 +0000 (Wed, 16 Dec 2015) | 5 lines 2015-12-16 Bernd Edlinger * unwind-generic.h (_Unwind_GetTextRelBase): Call __builtin_abort instead of abort to avoid dependency on stdlib.h. so I'll see if the problem goes away with newer GCC (I'm initially trying to clean up results with GCC 5 branch before going on to GCC 6 and mainline). -- Joseph S.
