--- Comment #1 from Tobias Burnus  ---
Forgot to mention: That's still the cc1 compiler
(libexec/gcc/x86_64-none-linux-gnu/11.0.0/cc1) not yet an offloading LTO.

The problem seems to be the followingat ipa-utils.h:246:
  /* We do not have this information when not in LTO, but we do not need
 to care, since it is used only for type merging.  */
  gcc_checking_assert (in_lto_p || flag_lto);


Here, we do not compile with LTO but write LTO for offloading.

That code is called by local_tree_p which was added by
r11-525-g03d90a20a1afcbb9c30da8d4adf4922b0685061f , Honza's
  "Avoid SCC hashing on unmergeable trees"
patch of May 20, 2020.
