PROBLEM:        (TKTQ51382  QAR 46989)  (Patch ID: OSF375-350289)
********
The code generator used an incorrect codegen sequence when doing
stack allocation within procedure prologs where the size of the
stack was very large (for example, when a structure is passed as an
entity rather than as a pointer).  This led to an improper instruction
sequence where a register value was dereferenced as an address pointer,
when in fact the register was a temp and had just been corrupted
by a previous function call which generated the error message

     "Segmentation fault (core dumped)".
