This bug is GCC PR middle-end/68733:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68733

The issue arises because structs larger than 64 bytes are passed by invisible reference and
the callee is responsible for copying.

Until this is resolved, the ICE can be avoided with the attached patch. Please apply if okay.

Thanks,
Dave Anglin
