           Summary: LLD executable segfaults with ld.bfd linker script
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal

Linker script

bash-4.4$ ld --verbose > main.link 
(Trim header and footer of  main.link. See attached)

bash-4.4$ clang hello.c -fuse-ld=lld -Wl,-T -Wl,main.link -o hello
bash-4.4$ ./hello
Segmentation fault

bash-4.4$ clang --version
clang version 13.0.0 (https://github.com/llvm/llvm-project.git
3c19b4f34d6a2a2fb628a3db9225a5167e363234)

The issue can be worked around by passing -Wl,--no-rosegment

This issue was previously fixed in 2017
(https://bugs.llvm.org/show_bug.cgi?id=35265), but it appears to have regressed
again at some point between llvm 9.0 and llvm 11.
