If you try to build it with this Dockerfile it works: https://github.com/docker-library/ruby/blob/master/2.4/alpine/Dockerfile. However I modified that to use jemalloc, so I guess it has something to do with jemalloc. Here is some steps I am doing to compile jemalloc and ruby:
wget https://cache.ruby-lang.org/pub/ruby/2.4/ruby-2.4.1.tar.gz
tar xzfv ruby-2.4.1.tar.gz
apk update && apk add ca-certificates && update-ca-certificates && apk add openssl
JEMALLOC_VERSION=4.5.0
wget -O jemalloc.tar.gz https://github.com/jemalloc/jemalloc/archive/${JEMALLOC_VERSION}.tar.gz
tar xzfv jemalloc.tar.gz && cd "jemalloc-${JEMALLOC_VERSION}"
make && make install_bin install_include install_lib
cd ruby-2.4.1
./configure --with-jemalloc
So first you can create an Alpine image with that Dockerfile, than:
docker run image_id /bin/sh
and you run the commands above

Hi, any update?
Updated by antoniobg (Antonio Borrero Granell) over 7 years ago
I'm also having a segmentation fault using the official ruby image. In my case, the error only happens when executing codeclimate-test-reporter.
Here's the log: https://gist.github.com/antoniobg/787521eec3d1e1019638a8cfe5b48fdd

I think this is due to mixture of glibc and jemalloc.
Here is a gdb output.
Thread 1 "miniruby" received signal SIGSEGV, Segmentation fault.

util.c:531 https://svn.ruby-lang.org/cgi-bin/viewvc.cgi/tags/v2_4_1/util.c?view=markup#l531
is call free(cwd) of jemalloc.
But cwd is a return value of getcwd(3) of glibc.

- Status changed from Feedback to Third Party's Issue
Took me time for several reasons:
- Had temporarily ran out of my docker hosts and had to prepare new one. This is my fault.
- The ruby:2.4-alpine's Dockerfile you linked kindly deletes compiler and other toolchains from the image. This prevents the procedure you told us to work. Please provide us a reproducible bug report. I ended up writing my own Dockerfile for this. https://github.com/shyouhei/docker-library/blob/master/%2313524/Dockerfile
- I am able to reproduce the bug now, and agree with @wanbe. I think this is either Alpine's or jemalloc's fault (or both).
The tiny C source code that comes with my Dockerfile is a file to generate SEGV without the needs of ruby. So at least I can say this has nothing to do with ruby. Please report this to alpine, to check if they support jemalloc or not. If they think it's ruby who's wrong, please tell us so. I'll take a deeper look at it.
Updated by thomasfedb (Thomas Drake-Brockman) over 6 years ago
Alpine package jemalloc in their main repo, so it would seem that they support it to some extent: https://pkgs.alpinelinux.org/package/v3.7/main/x86/jemalloc
Updated by mperham (Mike Perham) over 6 years ago
All, I modified Shyouhei's Dockerfile to use alpine3.7 and jemalloc 5.0.1 and it no longer segfaults:
FROM ruby:2.4.4-alpine3.7
Step 8/10 : ADD segv.c /tmp/segv.c

Removing intermediate container 039469e738f9

I would suggest trying Alpine 3.7 and see if you still have problems.
Updated by t_anjan (Anjan T) about 6 years ago
I used this Docker file (https://github.com/t-anjan/ruby/blob/jemalloc/2.4/alpine3.7/Dockerfile) which uses Alpine 3.7 and jemalloc 5.0.1 from the alpine repositories.
It still threw the same error.
