EControlC is the translation of run time error 217. The Win32
exception handler also sets error code 217 in case of an unknown
exception (the Win64 exception handler does the same, for that
matter). Apparently Win32 is not reporting that division-by-zero as
either STATUS_INTEGER_DIVIDE_BY_ZERO or STATUS_FLOAT_DIVIDE_BY_ZERO,
while Win64 does do this.
You can try debugging syswin32_i386_exception_handler in
rtl/win32/system.pp to see what exception Win32 reports instead.
