Starting with this commit: Paul Eggert : Mark _Noreturn error functions as cold 2019-04-18 00:35:18 the build of Emacs up to master (the last I tried is 75ee20364) fails (bootstrap-emacs.pdmp SEGMENT FAULT).
That's odd, since adding __attribute__ ((cold)) should affect only performance. If it causes a core dump, that suggests that there is a bug either somewhere else in Emacs (which __attribute__ ((cold)) happens to tickle) or in the compiler. Can you reproduce the problem when compiling with '-g3 -O0 -gdwarf-4' and get a backtrace, as suggested in etc/DEBUG?
