V8 doesn't use PAGE_SIZE, it uses sysconf(_SC_PAGESIZE). You mention 10.4.132 but that stack trace is from a different version, isn't it? Because SetDataReadOnly didn't exist back then. It crashes when trying to mprotect(PROT_READ) the command line flags, v8_flags. v8_flags is aligned to kMinimumOSPageSize and that _should_ be 16k on Android but you'll want to double-check that. It's defined in src/base/build_config.h.
