I am also having a very similar issue. I am using an M3 Max with 48GB memory. When I start debugging the code I can go through some breakpoints. One of the breakpoints that has no issues No issues is at a line that is similar to the line where another breakpoint is having the issueissues. When I arrive to the breakpoint where the issue is, it seems that I get stuck in an infinite loop (see the loop near locals). I can stop the debugger however lldb-mi runs in the background and increasingly uses more memoryMemory usage increasing!.
