I rebuild and installed Inline (Inline-0.44)
(had some problems getting make test to complete
but that's another story)

With an installed Inline and Inline​::C the
following code seg faults.

$ perl -MInline=_CONFIG_ -e1 /tmp/_Inline
Segmentation fault

I can't reproduce it with Inline-0.44
and a very recent bleadperl.

They did revert 5.8.1 a while ago to take out the patch that broke Inline
there. I think the problem wasn't really with Inline, but with Parse​::RecDescent

I can't reproduce the problem with 5.15.9 and 0.50. (I'm pretty sure I
wouldn't be able to reproduce it with *any* perl >= 5.6.0 and *any* version
of Inline >= 0.44.)

If the problem still exists for the OP, I think he should file a bug report
against Inline, not perl itself. (I don't know what the problem is, but I
doubt very much that it is a *perl* bug.)

Cheers,
Rob
