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=3Dlp64 -fopenmp @/tmp/ccHVgmel -o /tmp/ccdKIoRm.s

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