With --stdio, it works fine. I did a bit of investigation and found out that the TUI mode is failing because some symbol (kernel) is showing up with a huge (negative) size. I don't understand the connection between the TUI vs. tty browser and symbols. To reproduce: $ perf mem -t load rec my_test_program $ perf mem -t load rep $ perf mem -t load rep --stdio Debugging with TUI is a pain, so I stopped. I have a patch to improve perf mem a bit but I'd like to get this problem fixed first. Maybe you have a idea of what's going on.
