----------------------------------------
The fix for #8358 is build time solution. Unfortunately it turns out that this does not work so well for for distributions such as Fedora:

https://bugzilla.redhat.com/show_bug.cgi?id=1101811

The issues is that the SSE2 support is determined during build time, i.e. if builder supports SSE2, then the instructions are enabled. However, later when the packaged Ruby is executed on platform which does not support SSE2, it may result in issues as described in the above mentioned ticket.

Is there some way, how to resolve this issue in runtime rather than build time?
