Hi, we are seeing a segfault in qemu in the following code snippet in
zero_bss():
if (host_start < host_map_start) {
memset((void *)host_start, 0, host_map_start - host_start);
}
The elf doesn't have a data section, so host_start isn't mapped. I'm not sure
whether this is a qemu issue or the generated elf is no good.
Thanks,
Stephen
