Subject: perf-4.8.0-rc3: Segmentation fault
Date: Thu, 25 Aug 2016 13:49:41 +0300 [thread overview]
Message-ID: <CACVxJT8_dc4UGJz91W+Midbbx0rq02Vm5tnB1XTSP9kW6=vrDg@mail.gmail.com> (raw)
I profiled kernel allmodconfig build (don't ask) and perf tui reliably
segfaults when trying to enter annotation mode for any of the
individual functions. It segfaults immediately before even showing
menu with choices.
perf: Segmentation fault
-------- backtrace --------
perf[0x5451fb]
/lib64/libc.so.6(+0x33290)[0x7fcec0a80290]
perf(__map__is_kernel+0x26)[0x4bbcd6]
perf[0x54287c]
perf(perf_evlist__tui_browse_hists+0x94)[0x543e84]
perf(cmd_report+0x1a34)[0x434884]
perf[0x478471]
perf(main+0x6c6)[0x4237e6]
/lib64/libc.so.6(__libc_start_main+0xf0)[0x7fcec0a6d630]
perf(_start+0x29)[0x4238e9]
Steps to reproduce:
rm -rf ../xxx
mkdir ../xxx
make O=../xxx ARCH=x86_64 allmodconfig
perf record -e cycles make O=../xxx -k -j5
perf report
perf.data is 1.23 GB long , so be prepared.
