Than you very much, installed.

Other arches don't use GCPROs at all, instead they conservatively scan
the whole stack.  They do that by setting

   #define GC_MARK_STACK GC_MAKE_GCPROS_NOOPS

in the corresponding emacs/src/s/*.h.  This is the preferred way to
function, so if you can test it and confirm that it works as well under
AIX, we could set it for that OS as well.
