#13661: SAGA: IHNM: "createThread wrong scriptEntryPointNumber" when starting with
Benny
----------------------------+--------------------------
Reporter:  dwatteau         |      Owner:  (none)
    Type:  defect           |     Status:  new
Priority:  normal           |  Component:  Engine: SAGA
 Version:                   |   Keywords:  threading
    Game:  I Have No Mouth  |
----------------------------+--------------------------
 With either the English/Steam or French/GOG versions of IHNM (which
 trigger the SAMPLE.AD/SAMPLE.OPL warning), reinstalled from scratch to
 make sure the data is OK.

 For whatever reason, I can only reproduce this with the OSX PowerPC port:

 - It also happens with ScummVM 2.2.0, so it's not a recent regression.
 - Using different compiler versions doesn't fix the problem.
 - It's systematic on this port, i.e. playing with Benny is impossible
 there.
 - With Linux on the same PowerPC machine, it's fine. Maybe the OSX PowerPC
 environment is "luckier" in triggering this bug, especially if it's
 related to threading?

 Anyway, if I just do this:

 1. Start the game
 2. Choose Benny as a character
 3. Go down the stairs with Benny

 then the following error always appears in the console when Benny starts
 speaking to AM:

 {{{
 Script::createThread wrong scriptEntryPointNumber!
 }}}

 Skipping the dialogue or enabling/disabling the subtitles doesn't change
 anything.

 On Windows, I can't trigger the error message, but sometimes (1 out of
 10?) if I reproduce the steps above, Benny suddendly teleports to the
 cemetery, and if I go back to the previous room, he will resume reacting
 to AM, as if nothing happened.

 GDB and debug logs to be attached below.
