--- Comment #1 from Zheng Bao <fishbaoz at hotmail dot com> ---
1. -w pubnames is not correct. It should be -w --debug-dump=pubnames
2. Latest binutils is 2.45.1. There is no tag or branch 2.46 in the
https://sourceware.org/git/binutils-gdb.git
3. Below is what I got with the same command.
$ ../binutils-gdb/build245/binutils/readelf -w --debug-dump=pubnames
--dwarf-depth 2 PoC/SIGABRT_2
