            Bug ID: 27889
           Summary: jit.c:1178: internal-error: void
                    jit_event_handler(gdbarch*, objfile*): Assertion
                    `jiter->jiter_data != nullptr' failed.
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org

  Target Milestone: ---

Take example from https://llvm.org/docs/DebuggingJITedCode.html, save as
test.c. [ Probably works with any example, just listing what I used. ]

Verify compilation and error code:
...
$ gcc test.c; ./a.out; echo $?; rm a.out
255
...

Compile into llvm byte code:
...
$ clang -g -S -emit-llvm --target=x86_64-unknown-unknown-elf test.c
...

Verify that byte-code works:
...
$ lli test.ll; echo $?
255
...

Now run under gdb:
...
$ gdb -q -batch -ex run --args /usr/bin/lli test.ll
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".
[Inferior 1 (process 23272) exited with code 0377]
...

Ok, that went fine.  Using -ex "set debug infrun 1" we can also verify that
handle_jit_event was called:
...
  [infrun] handle_jit_event: handling bp_jit_event
...

Now install debuginfo for libllvm:
...
$ sudo zypper in libLLVM10-debuginfo
...

and try again:
...
$ gdb -q -batch -ex run --args /usr/bin/lli test.ll
Dwarf Error: Cannot not find DIE at 0x18a936e7 [from module
/usr/lib/debug/usr/lib64/libLLVM.so.10-10.0.1-lp152.30.4.x86_64.debug]
