Subject: [ruby-core:118232] [Ruby master Bug#14480] miniruby crashing when compiled with -O2 or -O1 on aarch64

Issue #14480 has been updated by vo.x (Vit Ondruch).


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.

Bug #14480: miniruby crashing when compiled with -O2 or -O1 on aarch64
https://bugs.ruby-lang.org/issues/14480#change-108728

* 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' \

	./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. Not sure yet. However, there is already lengthy analysis available in Fedora's Bugzilla [1]. Would be anybody able to help to resolve this issue?
