Incorrect list of basic blocks inside a function of libtiff compiled with clang O0 #26
Description
Using the serialized protobuf definitions from here, the list of basic blocks for function 0x1B380 of linux\libs\clang_O0\libtiff.so.5.4.0 are incorrect.
The ida pro ground truth(linux\libs\clang_O0\Block-idaBlocks-libtiff.so.5.4.0.pb) lists these blocks as children of 0x1B380:
- 0x1B380
- 0x1B3B2
- 0x1B3BE
- 0x1B3DC
- 0x1B3E7
- 0x1B3F2
- 0x1B42E
- 0x1B43B
- 0x1B45C
- 0x1B468
- 0x1B479
- 0x1B48B
The OracleGT ground truth(linux\libs\clang_O0\gtBlock_libtiff.so.5.4.0.pb) lists these blocks as children of 0x1B380:
- 0x1B479
- 0x1B48B
- 0x1B4A0
- 0x1B4C5
- 0x1B4DD
- 0x1B4F1
- 0x1B517
- 0x1B53D
- 0x1B563
- 0x1B589
- 0x1B5AF
- 0x1B5D5
- 0x1B5FB
- 0x1B61A
I cross referenced with both IDA & Binary Ninja, and the IDA pro ground truth is definitely correct - OracleGT is listing blocks which are not owned by 0x1B380. Is this a bug?
