POC
Hi, there.
An Invalid Memory Address Dereference problem was discovered in function
set_symbol_value in elflink.c in bfd of binutils 2.32 the latest code base. A
crafted ELF input can cause segment faults and I have confirmed them with
address sanitizer too.
Please use the "./ld -E $POC" to reproduce the bug.
The ASAN dumps the stack trace as follows:
