           Summary: [15 Regression] Ranger ICE
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal

Testcase, compile with -O2 on avr-elf

Recent work in Ranger seems to be causing an ICE on the avr-elf port.

Using a cross compiler for avr-elf compile the attached testcase with -O2 to
trigger this abort:

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Exact dup of bug 115009. The issue is ranger is not ready for pointers of
different size even though there are targets inside GCC that have it.
