This is "only" a problem on 64-bit machines installing from the generated .c files targeted at 32-bit architectures. It has something to do with the number of tag bits. A stage2 compiler does not crash.

Building the source distribution with --no-smart-indexing makes this problem go away.
I strongly suspect that some of the code generation approaches we use for switches
are not respecting the --cross-compiling option. (Most probably, it is the ones that
call int.bits_per_int/0 somewhere along the way.)

Fixed when we transitioned to Unicode.
