--- Comment #3 from Martin Liska <mliska at suse dot cz> ---
I have a nice reproducer:
$ cat ~/Programming/testcases/metrics.ii
void ReadElfBuildId(void *);
extern char __ehdr_start;
void ParseSmapsHeader() { ReadElfBuildId(&__ehdr_start); }
$ g++ ~/Programming/testcases/metrics.ii -fPIC -shared -O -m32 -o
/tmp/metrics.o -c
$ ./ld/ld-new /tmp/metrics.o -shared -melf_i386
./ld/ld-new: BFD (GNU Binutils) 2.34.50.20200401 assertion fail
../../bfd/elflink.c:14687
Segmentation fault (core dumped)
For completeness there's .s file:
$ cat metrics.s
.file "metrics.ii"
