Which model Pi are you using? I'm able to build on a Pi 3, so I wonder
if it's a difference in processors, where the Arm32 backend is using
something that it shouldn't.
Whether or not that guess is right, can you try running `gdb` in the
"ChezScheme" directory like this?
env SCHEMEHEAPDIRS=tarm32le/boot/tarm32le/ \
gdb tarm32le/bin/tarm32le/scheme
Disassembling around the failed instruction address (with `disassemble`
in gdb) should clarify what instruction is misused.
Thanks,
Matthew
