Thanks for the bug report.

It looks like this issue might be caused by certain versions of libc++.

Can you try changing the offsetof on line 502 of /projects/eng/software/src/opencilk/opencilk/cilktools/cilksan/disjointset.h to __builtin_offsetof and see if that resolves the issue for you?

Thank you. That resolved the issue and I'm able to finish the build now.
