Error (293007): Current module quartus_map ended unexpectedly.

Now that I check closely, I believe there is some weird behavior happening behind the compilation. (could be a bug)

I saw the Error (293007) occur with Quartus Standard 22.1 if using insufficient memory. When allocated a larger memory, it took me ~16m47s to finish the Analysis & Synthesis (using the +: indexed part-select) as compared to ~1m30s using other design. (without +: )

If I use Quartus Pro 22.4, both designs compiled successfully in 25 seconds. So something must have gone wrong with standard version.

I will file a case to the engineering team to investigate on this.
