Debugging with multiple inferiors

Opened this issue · 1 comments

Using multiple inferiors does not seem to work correctly.

I have three inferiors (all executables) running in the background:

  • file a
  • add-inferior --exec b
  • add-inferior --exec c
  • inferior 1
  • run &
  • inferior 2
  • run &
  • inferior 3
  • run &

A crash in 'b' shows correct source location , but:

  1. Locals says "Selected thread is running. = ??" and does not show any locals.
  2. Using print command for variables in scope says "No symbol X in current context." even though I clicked on the stack frame containing the symbol.
  3. Using "frame" command in CLI instead:
    1. frame 2
    2. frame
      • Here prints that it is still on frame #0 . GF seems to automatically set frame #0 again?

Using GDB by itself all of this works fine.

Using GDB 14.1 and gf2 commit 82889c4.

Another observation:

"Thread" panel shows multiple threads all having the same ID "1".

In reality using GDB these are named "1.1", "1.2", etc. because they are multiple threads for inferior 1.
