OpenCL Compiler Local Memory Address Space Splitter fails

Thank you for your reply, AKert. It is great to hear that my report is of some value. Meanwhile, I have found that the issue seems to be caused by reading from global memory and writing to an Intel FPGA channel in a single statement. When replacing

UTL_WRITE_CH(ch_1, data1[j]);
UTL_WRITE_CH(ch_2, buf_d2[i]);

with (make sure to use the actual types)

const my_type1 temp1 data1[j]
UTL_WRITE_CH(ch_1, temp1);
 
const my_type2 temp2 buf_d2[i]
UTL_WRITE_CH(ch_2, temp2);

the error goes away. It may or may not be related to also using char (8 bits) buffers.
