I can confirm that adding "-Oresolve-primitives -Ocps" to GUILE_OPTIMIZATIONS
in bootstrap/Makefile.am fixes the problem for me on 32-bit PowerPC on Debian.

I will have to figure out how to add "-Oresolve-primitives -Ocps" on 32-bit
big-endian conditionally so that it is not passed for other architectures.
