https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98341 --- Comment #9 from Arnaud Charlet --- The problem is somehow specific to m68k, for some unknown reason. There is nothing target specific in the change, no assumption is made on the underlying target. What we need now is a debugging session from someone who has a setup to reproduce.

I can certainly generate a backtrace in GDB, but I'm not an Ada expert which is why I reported the issue and hoped that the author of the change would be able to understand what the problem is. It could also be possible that the change makes some assumptions of the underlying ABI that may well be true for x86_64 but not m68k.

In other words, the bisect result isn't very useful here and I'd recommend investigating this change from scratch, getting a useful backtrace from gdb and understanding where this is crashing and then why.

--- Comment #3 from Marius Hillenbrand ---
Potential duplicate: I have seen very similar errors on s390x while reproducing
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98228
There, bisecting lead back to d119f34c952f ("New modref/ipa_modref optimization
passes"). In my tests, the first stage that is compiled with -flto then later
fails with errors of that kind (e.g., stage3 with config bootstrap-lto-lean).

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98341 --- Comment #2 from John Paul Adrian Glaubitz --- I have started to bisect this now. aa80d0650ce612d88a62d072b63c2523d547fca8 is still good while HEAD is broken. It will take a while until I have a result as I have to perform this bisecting on qemu-user.
