----------------------------+-----------------------------
 In the Dragon Trap Underground scene, use the turnstile and let the
 animation play. When it tries to loops for the 7th time, ScummVM crashes
 in
 [https://github.com/scummvm/scummvm/blob/52e89ef174ffb00e4baf34b734c13f9dfefb62be/engines/dragons/sequenceopcodes.cpp#L61]
 with:
 {{{
 Assertion failed: opCall._op < DRAGONS_NUM_SEQ_OPCODES, file
 /data/src/engines/dragons/sequenceopcodes.cpp, line 61

 }}}

 Debug logs with Debuglevel >=5 shows the loop for exactly 6 times before
 the crash happens when `Actor[2] execute sequenceOp` is logged the 7th
 time:
 {{{
 Actor[2] execute sequenceOp
 execSequenceOpcode(2) opSetFramePointerAndStop
 ARG_INT16(framePointer = 1162)
 set frame pointer 48A
 Frame blockSize: 896 width: 56 height: 64
 ActorId: 2 load frame header: (56,64)
 (...)
 Actor[2] execute sequenceOp
 }}}
