Shouldn't English posts be on ruby-core instead of ruby-dev?

Issue #11684 has been updated by ngoto (Naohisa Goto).
Status changed from Closed to Open
Assignee set to ngoto (Naohisa Goto)
ruby -v changed from ruby 2.3.0dev (2015-11-12) [sparc64-solaris2.10] to ruby 2.5.0dev (2017-12-19) [sparc64-solaris2.10]
Reopen because this is also observed with Oracle Developer Studio 12.6.

----------------------------------------
On Solaris 10, when compiling ruby with Oracle Solaris Studio 12.4 with -xO4 optimization option, the following test failure is observed during make test-all. (tested with r52550)
~~~
1) Failure:
TestPack#test_pack_unpack_atmark [XXXXX/test/ruby/test_pack.rb:548]:
<[nil]> expected but was
<[]>.
2) Failure:
TestPack#test_short_string [/XXXXX/test/ruby/test_pack.rb:735]:
<[1, nil]> expected but was
<[1]>.
15885 tests, 2225854 assertions, 2 failures, 0 errors, 50 skips
~~~
It seems that String#unpack is incorrectly compiled with Oracle Solaris Studio 12.4 with -xO4.
~~~
$ irb
irb(main):001:0> [1,2].pack('i2')
=> "\x00\x00\x00\x01\x00\x00\x00\x02" ###<== OK
irb(main):002:0> "\x00\x00\x00\x01\x00\x00\x00\x02".unpack('i3')
=> [1, 2] ###<== [1, 2, nil] is expected
~~~
It seems that PACK_ITEM_ADJUST() is wiped out by wrong optimization.
I think this is a bug of Oracle Solaris Studio 12.4.
The failure is not observed with -xO3 or lower optimization option.
It is also not observed by using Oracle Solaris Studio 12.3, even speficying -xO4 optimization option.
