            Bug ID: 30622
           Summary: symbol file: create_range_type: Assertion `TYPE_LENGTH
                    (index_type) > 0' failed
           Product: gdb
           Version: 12.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: parkerdahn at gmail dot com
  Target Milestone: ---

Currently workout out of WSL using Qemu 8.0.2, connecting gdb 12.1 to it, and
if I provide the kernel file for symbols gdb crashes.

I've tried several things but it always crashes when it tries to look up a
memory address, from a search, a breakpoint, or if I continue and stop
execution, whenever it stops it will crash

However if I do not provide the file for symbols it does execute just fine
