On a clean checkout, "make" failed for all three of them with this error: sysdep.c:1795:22: error: variably modified ‘sigsegv_stack’ at file scope 1795 | static unsigned char sigsegv_stack[SIGSTKSZ]; | ^~~~~~~~~~~~~ make[2]: *** [Makefile:377: sysdep.o] Error 1 make[2]: Leaving directory '/home/eric/dev/emacs-26/src' make[1]: *** [Makefile:421: src] Error 2 make[1]: Leaving directory '/home/eric/dev/emacs-26' make: *** [Makefile:1107: bootstrap] Error 2 This is on Arch Linux, I can send the config.status file for any of the branches if that would help. Master builds fine. Is this somehow expected, ie I've done something wrong, or shall I open a bug report? Thanks, Eric
