Patch Set 2:

> Should it do so then? I'm not too familiar with the whole jit scheme in GDB, but it sounds like the breakpoint locations should go away when we free the objfile?

See my response to Simon above - I was hoping that someone who knows it more can chime in and clarify this bit. The current behavior looks wrong indeed but I am hesitant to change generic objfile behavior without any confirmation from someone who knows this better.

The fact that there is currently a dedicated flag for a similar shared library case makes me suspect it may be intentional (otherwise it could just use generic objfile behavior).

The `breakpoint_free_objfile` was introduced in 2f202fde0a4586f88b98439b436e7b0bb1336b26 long time ago and I don't see any rationale mentioned there.
