I don't understand why this change was applied. This should be either enabled everywhere or disabled everywhere, not enabled on some random platforms. Please note that this should not be issue on aarch64 for a while.

Or was the issue exhibited somewhere recently? The commit does not elaborate about it.

We had a report of this in Gentoo today on amd64: https://bugs.gentoo.org/949016. Using setjmp worked. Having read over the discussions with the GCC developers, I don't think `__builtin_setjmp` should ever be used if `setjmp` is available. ---------------------------------------- Bug #14480: miniruby crashing when compiled with -O2 or -O1 on aarch64 https://bugs.ruby-lang.org/issues/14480#change-111700 * Author: vo.x (Vit Ondruch) * Status: Closed * ruby -v: ruby 2.5.0p0 (2017-12-25 revision 61468) [aarch64-linux] * Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN ---------------------------------------- Recently, it is not possible to build Ruby 2.5.0 on aarch64 on Fedora Rawhide, because miniruby fails during build: ~~~ ... snip ... ./miniruby -I./lib -I. -I.ext/common -n \ -e 'BEGIN{version=ARGV.shift;mis=ARGV.dup}' \ -e 'END{abort "UNICODE version mismatch: #{mis}" unless mis.empty?}' \ -e '(mis.delete(ARGF.path); ARGF.close) if /ONIG_UNICODE_VERSION_STRING +"#{Regexp.quote(version)}"/o' \ 10.0.0 ./enc/unicode/10.0.0/casefold.h ./enc/unicode/10.0.0/name2ctype.h generating encdb.h ./miniruby -I./lib -I. -I.ext/common ./tool/generic_erb.rb -c -o encdb.h ./template/encdb.h.tmpl ./enc enc generating prelude.c ./miniruby -I./lib -I. -I.ext/common ./tool/generic_erb.rb -I. -c -o prelude.c \ ./template/prelude.c.tmpl ./prelude.rb ./gem_prelude.rb ./abrt_prelude.rb *** stack smashing detected ***: <unknown> terminated encdb.h updated ... snip ... ~~~ This might by Ruby or gcc issue.
