Other times it will segfault in other places. It seems pretty random.

Has duplicate Ruby master - Bug #18050: Cannot build ruby-2.7.4 on NetBSDOpenActions

Updated by xtkoba (Tee KOBAYASHI) 4 months ago

First, it should be clarified that it is the already installed /usr/local/bin/ruby (version 3.0.1p64) that segfaults here.

I guess that the source comes directly from a Git repository, as prelude.rbinc should be prebuilt in a release tarball which should be tried out for self-containedness.

To avoid using already installed Ruby interpreters try adding the option --with-baseruby=no to ./configure.

This turned out to be an issue with miniruby when the NetBSD kernel has PaX ASLR (Address Space Layout Randomization) enabled. The following patch, applied post-configure, works around the problem.

Maybe only miniruby needs to disable ASLR?
