Comment (by PushmePullyu):

 It should work in a VM (I used real hardware with a 2+2HT core Pentium
 Gold 4417U).

 Build config was just:
 ./configure --disable-all-engines --enable-debug --disable-optimizations
 --enable-engine=sword1

 One could also use --enable-tsan (or use valgrind instead).

 I observed more crashes with video mode set to SDL Surface, but that could
 have been random.

 Valgrind with helgrind should prove helpful in debugging this, e.g.
 something like:
 valgrind --tool=helgrind --log-file=~/sword1_%p.log ./scummvm

 useful valgrind options:
 --scheduling-quantum=<number> (default is 100000)
 --free-is-write=yes (default is no)
 If you get to many bogus errors you can create a suppressions file:
 --gen-suppressions=<yes|no|all>
 --suppressions=<filename>

 Just ping if you need more testing done.
