Closed as program error.
Error description
When compiling with options -O and -q64, the application may encounter a segmentation fault and output incorrect sizeof values for some structures. These structures, when compiled, may reserve less space than they require.
Local fix
N/A
Problem summary
Users running with optimization on. Autofoliation assumes that all parameters are register size because the appropriate function to map parameters has not yet run. When it does encounter a parameter that is larger than register size, it only allocates a single register for it, which ultimatetly throws off the calling sequence.
Problem conclusion
If we encounter a parameter that will not fit into a single register, don't autofoliate the procedure.
