PR modula2/111510 runtime ICE findChildAndParent has caused internal runtime error

This patch fixes the runtime bug above.  The full runtime message is:
findChildAndParent has caused internal runtime error, RTentity is either
corrupt or the module storage has not been initialized yet.  The bug is
due to a non nul terminated string determining the module initialization order.
This results in modules being uninitialized and the above crash.  The bug
manifests itself on 32 bit systems - but obviously is latent on all
targets and the fix should be applied to both gcc-14 and gcc-13.
