Here is the test in python (you can chooses any midifile and adapt the variable midifile accordingly).
You can also adapt the lib variable.

Title:
  [SRU] Players terminate after stopping and restarting

Status in fluidsynth package in Ubuntu:
  Fix Released
Status in fluidsynth source package in Mantic:
  Incomplete
Status in fluidsynth source package in Noble:
  Fix Released

Bug description:
  [ Impact ]

  Fluidsynth 2.3.3 has an issue where it will terminate upon start/stop
  of playback of a midi song, causing issues for a multitude of players
  including EasyABC. This will cause said player to be unable to
  playback again and perhaps even crash. See
  https://github.com/FluidSynth/fluidsynth/issues/1272, fix in
  https://github.com/FluidSynth/fluidsynth/commit/377ab9db2f87bc407eeb940e0361edc77da77055.
  This is the included patch with the upload of
  2.3.3-2.1ubuntu-0.23.10.1

  [ Test Case ]

  * Begin midi playback in any midi player using fluidsynth from the
  terminal

  * Stop midi playback

  * Attempt start again

  * Error in terminal: fluidsynth: error: The maximum playback duration
  has been reached. Terminating player!

  [ What could go wrong ]

  This is actually a fix for a regression that was found in version
  2.3.3 of fluidsynth and fixed for 2.3.4, which can be found in noble.
  I think the only thing that can go wrong here is that this patch is
  not the actual fix and we need to find more solutions within.

  I have tested this in my PPA and it *seems* to fix it, but it would be
  nice if the original reporter could verify once this lands in
  proposed.

  [ Other information ]

  Included below is the original report, in which case the reporter
  deduces that the problem is the binary being spat-out is the 2.3.2
  version from the 2.3.3 sources. This is not the case, as it appears to
  be confusion due to the -2.1 Debian revision number. I assure, this is
  definitely the 2.3.3, and the bug, per the github link in the Impact
  section, is pertinent to this version.

  ---

  The latest package of fluidsynth should include the sources from
  version 2.3.3 but the binary includes only version 2.3.2

  This version has a bug (see
  https://github.com/FluidSynth/fluidsynth/issues/1272), which leads to
  problems in EasyABC.

  Please include the latest version 2.3.3 from upstream in the ubuntu
  package.
