This is almost certainly this issue:

  https://github.com/ivmai/bdwgc/issues/409

which span out into this issue:

  https://github.com/ivmai/bdwgc/issues/432

which was fixed with this commit:

  https://github.com/ivmai/bdwgc/commit/8868a7a3cc70e5302f7835a2040a9726238b4f6a

I'm not sure which version of libgc that fix is in though.

Thanks,
Andrew
