Hi there,
I crashed `readelf -w` with a fuzzer. The original error message was "readelf:
dwarf.c:2336: void display_discr_list(unsigned long, dwarf_vma, unsigned char
*, const unsigned char *, int): Assertion `uvalue > 0' failed."
- Compiler: clang12
- Platform: Ubuntu 18.04.5 LTS, x86_64
- Reproduce: run `readelf -w poc`
