I found something suspicious, get_relocations(s) return all the count of 
relocation and write to rap file, but actual count is less, because 
ignore the reloc with section=0.

This issue is similar to ticket #4781, maybe the same.

reduce count or write all relocs in rap ? I do not know which is the 
right solution.
