Memoranda, a 32-bit commercial game, in its version sold on gog.com, crashes on launch with a segmentation fault, before even showing the game window.

Here is a backtrace generated with gdb:

I first saw the crash on a Debian Bullseye/Sid with the following specs:

• Linux 5.4.13 and 5.4.19
• Mesa 19.3.3, cf. glxinfo.gz
• X.org 1.20.7
• X.org amdgpu driver 19.1.0

I reproduce this crash reliably with a build of current master (19.3-branchpoint-3779-g0103f02acb1).
