This caused ScummVM to stop responding for a little while...but that only happened once. And gameplay continued.

After escaping the Pterodactyl's nest you land in the water and go back to land. Then a musical cue plays and the girl talks to you. The theme that plays here plays much too fast and there's a long silent pause afterwards when it's supposed to loop...after a certain amount of time the song starts up again playing too quickly and loops again after another silent pause. This tells me that a possible explanation might be that it loops at the correct moment but the song plays too quickly to be timed to the loop...or something. I get these messages in the console:

ScummVM version 1.2.0svn52122

Savegame attached. Just jump out of the nest and watch the sequence.

    Pterydactyl's Nest - Jump out to see music bug

     
  • Filippos Karapetis

    This bug only seems to occur when the Adlib driver is chosen. It doesn't occur with the GM driver

     
  • Filippos Karapetis

    This only occurs when Adlib music is chosen. It works correctly with GM music. To reproduce in any version, just warp to room 297 and jump off the nest

    Update (with the help of waltervn): The song playing is song 57, and there seems to be a problem with its Adlib channels. The silence heard is actually coming from the song itself (tested with SV). This seems to be a broken song resource, i.e. a genuine game bug, but we need to verity this in DOSBox and check if it works there
