Hi,

	While trying to test my tmp.perf/ui_browser.horiz_scroll branch
with 'perf mem report' to allow that kind of browsing on the TUI, as of
now it works only on --stdio mode, using the right/left arrow keys, I
noticed this in acme/perf/core (but I saw it too in many previous
revisions, trying to bisect it):

[root@zoo ~]# perf mem record -a
^C[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 3.072 MB perf.data (647 samples) ]

[root@zoo ~]# perf mem report
perf: Segmentation fault

Have you noticed this? No time to look at this now :-\
