P.S.: The failure mode was:
failure using sh64-elf-run .
success using sh64-elf-gdb .
failure when re-loading / re-running with sh64-elf-gdb .
... which was all because ininitialized memory beyond the stack
was read (i.e. a smidge outside of all the sections that the program
claimed to use), and the zero-initialized memory of gdb happended to
give the right result.
