SuperTux Version

supertux2 dev v0.7.0-beta.2 - d408848 (master)

System Information

Debian Sid amd64, Linux kernel 6.18.8+deb14-amd64

Expected Behavior

After all profiles are deleted, options Rename, Reset, Reset all, Delete, Delete all are greyed out.

Actual Behavior

Options Rename, Reset and Delete are not greyed out and in fact can be used. When the options are used in that case, the game crashes or asks about big-number-named profiles, empty-named profiles or garbage-named profiles (example below).

Steps To Reproduce Actual Behavior

  1. Enter the main menu.
  2. Enter options.
  3. Select extras.
  4. Go to the Select Profile section.
  5. Select Delete all.
  6. Confirm the choice.
    (alternatively repeat steps 5 and 6 with the option Delete)
  7. Observe it is possible to reset, rename or delete a profile.

Additional Information

Since the bug can be exploited to crash the game, I tried to record the crashes just in case.
here is normal terminal output

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
