#15546: Dreamweb French crashes right at the start

 When compiling with ASAN on macOS, playing the French CD version of
 Dreamweb crashes right at the start. Just skip the intro and watch it
 crash.

 The issue does not happen with the English or the Czech versions of the
 game. This seems specific to the French version.
 I also downloaded again a fresh version of Dreamweb from our website and
 got the same issue. So if the issue is due to corrupted game files this
 means it is corrupted in our download.

 This happens with current master, but I verified it already happened with
 code from 2 years ago (Dec 2022 - commit 2521169). So this is not a recent
 regression.

 The ASAN report is:

 This is on a mac M1 with macOS Sonoma.
