            Bug ID: 48168
           Summary: Assert triggered in ld when compiling with
                    -fsanitize=hwaddress
           Product: compiler-rt
           Version: 11.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: hwasan
          Assignee: unassignedbugs at nondot.org
          Reporter: aanderso at tcd.ie
                CC: llvm-bugs at lists.llvm.org

When compiling the SPEC CPU2017 benchmarks on Linux x86_64, I tried using
hwasan with -fsanitize=hwaddress -Wl,--no-relax.

I see an assert triggered in ld -- details are below. I am not entirely sure if
hwasan on x86 is supposed to be working at the moment, but I can volunteer to
test any changes. The assert being triggered is this one:
http://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=bfd/elflink.c;h=998b72f2281c5b9b5482795b9b55dfffe284ee23;hb=2cb5c79dad39dd438fb0f7372ac04cf5aa2a7db7#l14788

To be honest, I'm not sure if I should file this as a bug against gdb, but if
someone familiar with the workings of hwasan can test it with binutils 2.35.1
on x86, perhaps that testing will generate a bug report naturally with much
more context than I could provide.
