-Subject: [PATCH] debuginfod/debuginfod-client.c: correct string format on
- 32bit arches with 64bit time_t
-
-Use intmax_t to print time_t
-
-time_t is platform dependent and some of architectures e.g.
-x32, riscv32, arc use 64bit time_t even while they are 32bit
-architectures, therefore directly using integer printf formats will not
-work portably, use intmax_t to typecast time_t into printf family of
-functions

-glibc 2.34 calls pthread_kill from the raise function. Before raise
-directly called the (tg)kill syscall. So allow pthread_kill to be the
-first frame in a backtrace where raise is expected. Also change some
-asserts to fprintf plus abort to make it more clear why the testcase
-fails.
