--- Comment #2 from Shaohua Li <shaohua.li at inf dot ethz.ch> --- Compiler: gcc11 & clang12 Platform: Ubuntu 20.04 LTS, x86_64 Summary: I compiled Binutils with gcc11 and clang12 separately, then run with `readelf -w poc`. I found that the last line in two outputs were different. For gcc11, it was: "00000044 000000000000004e 100e4500 FDE..." For clang12, it was: "00000044 0000000000000000 100e4500 FDE..." Then I checked the source code and found that the guard in dwarf.c:8802 would be evaluated differently in two compiled binaries. The root cause is in dwarf.c:8797, where `look_for` would be a negative value in the clang12-compiled binary. -- You are receiving this mail because: You are on the CC list for the bug.
