When testing for upgrade to Unicode 11.0.0, I'm running into the following error:

$$ ./ruby test/runner.rb test/ruby/test_m17n.rb

This can go on and on until I interrupt it with Ctrl-C, as done above. The errors happen in the following files:

test/ruby/test_m17n.rb
test/ruby/test_string.rb
test/ruby/test_regexp.rb

although running just test/ruby/test_string.rb or test/ruby/test_regexp.rb alone works fine, but running test/ruby/test_m17n.rb, even if alone, produces the errors.

The numbers at the start of the error messages are usually very low (as above), but I have seen numbers up to around 27000 also on several occasions but rarely. The file name (emoji_iso2022_kddi.so) and the address (0x40000) are always the same. The numbers after ruby (I guess they are process numbers) vary with each run, as do the numbers at the start.

My current guess is that these errors should not appear if the various .so files are really relocatable, but I'm no expert in linking/loading details.

If there's any other way to run the tests, e.g. with some special option(s) to test/runner.rb or so, I'd appreciate a hint.
