https://trac.webkit.org/changeset/192682 enabled FTL JIT on EFL Linux X86_64.
Since then regress/script-tests/double-pollution-putbyoffset.js.dfg-eager
regularly stucks in an infinite loop.

It isn't an EFL related bug, but an FTL JIT bug on Linux,
because I found similar errors on the GTK bot too:
