Issue #11553 has been updated by Vit Ondruch.

Status changed from Open to Rejected

----------------------------------------
Bug #11553: Disable by default the DTrace support on Linux systems.
https://bugs.ruby-lang.org/issues/11553#change-54300

* Author: Carlos Alberto Lopez Perez
* Status: Rejected
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.3.0dev (2015-09-26 trunk 51943) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
The issue is the following:

* Linux has an unnofficial implementation of DTrace (dtrace4linux).
* However, this still don't works as expected and causes either build failures or \
                segfaults at runtime when is enabled on the Ruby build.
  * Examples:
     * https://github.com/dtrace4linux/linux/issues/111
     * https://github.com/dtrace4linux/linux/issues/116


So, I propose to (by default) disable dtrace support on Linux systems.

Otherwise users that try to build Ruby on a Linux system with dtrace4Linux installed \
(me for example), will end with a broken build.

Linux users willing to try this feature, can still pass the --enable-dtrace flag to \
enable it.

Patch attached.
