Issue #15290 has been updated by Kulikjak (Jakub Kulik).


I just managed to build latest Ruby 2.6.0 preview 3 and this issue is not there so it might be fixed.

It is however a little bit weird that this issue appeared with version 2.5.3 and was not present at 2.5.1. But maybe it was there always and tests didn't find it.

Bug #15290: load_from_binary Bus error on Solaris sparc
https://bugs.ruby-lang.org/issues/15290#change-74812

* Author: Kulikjak (Jakub Kulik)
* Status: Open
* Priority: Normal
* Assignee: nagachika (Tomoyuki Chikanaga)
* Target version: 
* ruby -v: ruby 2.5.3p105 (2018-10-18 revision 65156) [sparcv9-solaris2.11]
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: REQUIRED
----------------------------------------
When we updated to recently released version 2.5.3, one test on sparc started to fail:

~~~
/.../ruby-25/ruby-2.5.3/test/ruby/test_iseq.rb:403: [BUG] Bus Error at 0x000000010d1de3ec
ruby 2.5.3p105 (2018-10-18 revision 65156) [sparcv9-solaris2.11]

-- Control frame information -----------------------------------------------
c:0029 p:---- s:0169 e:000168 CFUNC  :load_from_binary
c:0028 p:0013 s:0164 e:000163 BLOCK  /.../ruby-25/ruby-2.5.3/test/ruby/test_iseq.rb:403 [FINISH]
...
~~~

This is happening on sparc only (we also build the same thing for intel) and was not present in version 2.5.1. All other tests work.

Logs from configuration, build and whole test attached.
