Compilation and simulation issue

Hi, I have two questions.

1.I'm using gcc-11 and Python 3.8 to compile this project, but I encountered the following error message (*1). It seems to be caused by the newer version of gcc because I can compile it successfully with gcc 9.3. I'm wondering if you have any plans to support newer versions of gcc.

2.I'm running the test_force.Default.ELF generated by gcc 9.3 on Spike, but I'm getting a "memory address is invalid" error. I would like to know if there is any way to fix this issue.

Access exception occurred while loading payload ./test_force.Default.ELF: Memory address 0x50000000 is invalid
