| |
Hi,
When trying the following command line with perf from tip,git, I got:
$ perf record --group -c 100000 -e '{branch-misses,branches}' -a -o - sleep 1| perf report --no-group -F sample,cpu,period -i - # To display the perf.data header info, please use --header/--header-only options. # Segmentation fault (core dumped)
(gdb) r report --no-group -F sample,cpu,period -i - < tt Starting program: /export/hda3/perftest/perf.tip report --no-group -F sample,cpu,period -i - < tt # To display the perf.data header info, please use --header/--header-only options. #
Program received signal SIGSEGV, Segmentation fault. hlist_add_head (h=0xeb9ed8, n=0xebdfd0) at /usr/local/google/home/eranian/G/bnw.tip/tools/include/linux/list.h:644 644 /usr/local/google/home/eranian/G/bnw.tip/tools/include/linux/list.h: No such file or directory. (gdb)
Can you reproduce this? Thanks.
