quartus prime software quit unexpectedly

I have problem with synthesis. I can't find any information about this error code.  

Here is the report:

Address bits: 64

Build: 196 

Edition: Standard Edition 

----------------------------------------------------------------- 

I have found the code which causes this issue. But I don't know why the code causes the problem. Also, I don't know how to solve it. Here is the code: 

initial 

begin 

$readmemb("../data/file1.txt", rom1); 

$readmemb("../data/file2.txt", rom2); 

end 

It seems tha quartus doesn't allow me to initialize two ROMs in one verilog file. After I remove either one of the two $readmemb statement, quartus can synthesis successfully. 

I have also tried used two seperate initial blocks, each block contains one $readmemb. This doesn't solve the problem. 

I use the template provided by quartus to implement the two roms. Rom is inferred correctly.  

How do I solve this problem? I need to initialize multiple roms and rams in my project. 

Thank you!
