2030	Array Slice Assignment not simulatable	Jens Frenkel	Martin Sjölund	"The following models is not simulatable because codegeneration/simulation runtime generates invalid code.

  Real X1[5,2];
algorithm
  for i in 1:2 loop

The problem is that tmp2.dim_size ist not set and ""copy_real_array_data_mem"" wrote in other memory than reserved for $PX1. Maybe indexed_assign_real_array should set tmp2.dim_size."	defect	closed	critical	1.9.1	Code Generation	trunk	worksforme	array slice assignment	Willi Braun
