| |
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 -------- backtrace -------- perf[0x52a08b] /lib64/libc.so.6(+0x34960)[0x7f8726860960] perf(addr_map_symbol__inc_samples+0xbb)[0x47abfb] perf[0x42e93f] perf(hist_entry_iter__add+0x102)[0x4d9632] perf[0x42e7ba] perf[0x4bc4c3] perf[0x4bc9c1] perf[0x4bf6b9] perf(perf_session__process_events+0x390)[0x4be1b0] perf(cmd_report+0x1038)[0x42faf8] perf(cmd_mem+0x3ec)[0x44c69c] perf[0x479113] perf(main+0x60a)[0x420a5a] /lib64/libc.so.6(__libc_start_main+0xf0)[0x7f872684bfe0] perf[0x420b79] [0x0] [root@zoo ~]# perf evlist cpu/mem-loads/pp cpu/mem-stores/pp [root@zoo ~]#
Have you noticed this? No time to look at this now :-\
