--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Huh, I remember a very similar report from the past, unable to reproduce on
SUSE packaged GCC.  Can you attach the console output when you add -v
to the compiler command?  Can you install debuginfo so we can get a backtrace
as to where the error happens?

Perhaps Ubuntu has the offloading and non-offloading compiler configured
differently, one with zstd compression support and the other without?

Perhaps built separately, once with zstd-devel in the buildroots and once
without?  Dunno.
What does
x86_64-linux-gnu-accel-nvptx-none-gcc -v
print?

Note that that one ICEs on matching compression algorithms which here
the ICE notes the compressed data stream is corrupt.

There must be sth subtle going on ...

I hope that -save-temps will save the offload images fed to the nvptx-none
lto1.
Matthias, can you attach them?  That is,

 /usr/lib/gcc/x86_64-linux-gnu/10/accel/nvptx-none/lto1 -quiet -dumpbase
ccwItcGR.o -m64 -mgomp -auxbase ccwItcGR -version -fno-openacc -fPIC
-foffload-abi=lp64 -fopenmp @/tmp/ccHVgmel -o /tmp/ccdKIoRm.s

look into /tmp/ccHVgmel which should contain a (list of) object file name(s)
to pass along.

call.

            * lto-common.c: Initialize file_data->lto_section_header
            before lto_mode_identity_table call.  It is needed because
            it decompresses a LTO section.
