I figured object files contain the version of the compiler, so the previous
version was GCC: (GNU) 10.2.1 20201110 (built from releases/gcc-10 at that
date)

Try this:
touch a.a a.o
gcc -save-temps -Wl,-debug -o a a.o a.a -ldl
Outputs:

/usr/bin/ld -plugin /usr/lib/gcc/x86_64-pc-linux-gnu/9.3.0/liblto_plugin.so

The ldlang.c:6868 assertion bug was fixed in binutils.
That leaves the -save-temps/gcc driver issue.

Since the assertion is in `ld`, I've also reported the issue with some new
details here https://sourceware.org/bugzilla/show_bug.cgi?id=24567

Without -save-temps, generated name is random. So while there's some issue
there, too, because '-ldl.res' doesn't make much sense as an output for %u.res,
it is

Also, the issue did not happen with 8.3.0 and the same binutils. An I also get
this assertion when building with i686-musl-linux cross-compiler, but

The build of harfbuzz 2.3.1 with gcc 8.2.0 succeeds.
I can also confirm that re-building all dependencies of harfbuzz with 8.2
branch rev268702 also succeeds.
So the issue is with 8.2.1

One question. Are the LTO object files built with gcc 8.2.0 supposed to be
compatible with those built with 8.2 branch tip? I have static library
dependencies that are also compiled with

--- Comment #5 from ohaiziejohwahkeezuoz at xff dot cz ---
Reproducing this might be somewhat complicated, because harfbuzz has some
dependencies, which would also needed to be built. But I have captured the
failing command, and can run gdb on it

See Comment 1 please.
CFLAGS for gcc are in Comment 2. Just "-ggdb -Og".
Failing cross-compiler is built on Arch Linux, with the default compiler:
# gcc --verbose

The main problem is elsewhere (read_cgraph_and_symbols looks just like some
cascading assertion failure because of some other segfault). I recompiled gcc
with -Og -ggdb and managed to
