Comment (by PushmePullyu):

 For reference: PR is at https://github.com/scummvm/scummvm/pull/5713

 Since the removal of the static fixed the AGS crash, there seems to be
 some problem with DSO unloading and dtors of statics.

 Dtors registered from a DSO _seem_ to run on program exit instead of SO
 unload (or maybe they are run twice). Perhaps your libc / build is not
 using !__cxa_atexit?

 From the gcc manpage:

 -fuse-cxa-atexit
 Register destructors for objects with static storage duration with the
 "!__cxa_atexit" function rather than the "atexit" function. This option is
 required for fully standards-compliant handling of static destructors, but
 only works if your C library supports "!__cxa_atexit".
