Hi,
I was running a couple of tests with perf mem from tip.git and
found that perf mem -t load rep was failing only in TUI mode.
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.
I usually avoid the TUI by not installing slang-devel.
But, trying out Linus' current tip (a0e4467726c - post 3.18) this seems
to work fine:
perf mem -t load rec ls
perf mem -t load rep
But kernel version for the box is 3.16.6-203.fc20.x86_64.
