Web Compatibility Support • Crash on metacpan.org

I get a crash when attempting to visit a page on metacpan.org, for example https://metacpan.org/dist/DBD-Pg

This is Pale Moon 34.1.0 on illumos (Tribblix).

Wondering if it's just me, or whether it's a more general problem.

Relevant top of stack below, but all that shows me is that it's inside libxul, and as this is illumos it may be more useful if you got a dump off something you're more familiar with
