Describe the bug

Bug occurs in emu/unicorn/generic.py in function do_mapping.

Line that causes the issue.

uc.mem_write(seg.start_ea,ida_bytes.get_bytes(seg.start_ea,seg.size()))

API get_bytes() is expecting a value less or equals to 4GB (0xffffffff).
Unicorn won't let map 4GB segment as well.

Correction: Split big segment in sub segments of size 1GB ?

Versions (please complete the following information):

  • IDA 8.2
