            Bug ID: 106642
           Summary: cc1 compiler hangs when cross-compiling ring_buffer.c
                    (from kernel/events) on Aarch64
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pivanov at hotmail dot com
  Target Milestone: ---

Compiler hangs forever and consumes all available memory when cross-compiling
android kernel tree.

The file that it hangs on is kernel/events/ring_buffer.c

You may find the preprocessed ring_buffer.i attached.

--------------------------------------------

The same command line hangs on the attached preprocessed file (ring_buffer.i)
so the bug should be fully reproducible.

I did try to alter options from the command line above but couldn't make it to
compile no matter what options have been removed.
