As I told you, `make install` is needed to make Ruby work. Running

One more reason for https://bugs.ruby-lang.org/issues/13620 maybe? ;)

[ruby-core:87845] [Ruby trunk Bug#14900] Extra allocation in String#byteslice
From:

Issue #14900 has been reported by janko (Janko Marohnić).
----------------------------------------
Bug #14900: Extra allocation in String#byteslice
https://bugs.ruby-lang.org/issues/14900
* Author: janko (Janko Marohnić)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin17]
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
When executing `String#byteslice` with a range, I noticed that sometimes the original string is allocated again. When I run the following script:
~~~ ruby
require "objspace"
string = "a" * 100_000
GC.start
GC.disable
generation = GC.count
ObjectSpace.trace_object_allocations do
string.byteslice(50_000..-1)
ObjectSpace.each_object(String) do |string|
p string.bytesize if ObjectSpace.allocation_generation(string) == generation
end
end
~~~
it outputs
~~~
50000
100000
6
5
~~~
The one with 50000 bytes is the result of `String#byteslice`, but the one with 100000 bytes is the duplicated original string. I expected only the result of `String#byteslice` to be amongst new allocations.
If instead of the last 50000 bytes I slice the *first* 50000 bytes, the extra duplication doesn't occur.
~~~ ruby
# ...
string.byteslice(0, 50_000)
# ...
~~~
~~~
50000
5
~~~
It's definitely ok if the implementation of `String#bytesize` allocates extra strings as part of the implementation, but it would be nice if they were deallocated before returning the result.
