Has this been discussed and I missed it?
I'm seeing a duplicate LOAD section from /proc/vmcore as shown in this
excerpt from readelf -l vmcore:
Program Headers:
Type Offset VirtAddr PhysAddr
FileSiz MemSiz Flags Align
...
LOAD 0x0000000000001f08 0xe000000000001000 0x0000000000001000
0x0000000003fff000 0x0000000003fff000 RWE 0
>> LOAD 0x0000000004000f08 0xa000000100000000 0x0000000004000000
0x0000000000d46000 0x0000000000d46000 RWE 0
>> LOAD 0x0000000004d46f08 0xe000000004000000 0x0000000004000000
0x0000000000d46000 0x0000000000d46000 RWE 0
LOAD 0x0000000005a8cf08 0xe000000004d46000 0x0000000004d46000
0x00000000032ba000 0x00000000032ba000 RWE 0
...
Note the two sections with PhysAddr x0000000004000000,
one at VirtAddr=0xa000000100000000, and the other at
VirtAddr=0xe000000004000000. They are at different offsets
in the file, and using objdump -s --section=loadN, I believe
they contain identical data. It's a lot of redundant data
in the dump file. I assume the problem is in the purgatory
code that sets up the elf map? Is it necessary to include
this section with both of its virtual aliases for some reason?
