   If you Guix build for Windows, and call objdump on libbitcoinconsensus-0.dll, you’ll find it uses a non-static libssp:

    0objdump -x src/.libs/libbitcoinconsensus-0.dll

   DLLs should be built with a static libgcc/stdc++/ssp:

   This has been an issue since we switched to using Guix for the 22.0 release.
