Subject: perf_guest default bug
Date: Fri, 02 Mar 2012 12:00:01 -0700 [thread overview]
Message-ID: <4F5118B1.5070406@gmail.com> (raw)
Similar to my last email, this patch is not in urgent trees or Linus'
yet the problem exists in Linus' tree:
https://lkml.org/lkml/2012/2/17/82
$ /tmp/pbuild/perf record -a -- sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.319 MB perf.data (~13935 samples) ]
Segmentation fault
Root cause is the perf_guest setting.
$ /tmp/pbuild/perf --version
perf version 3.3.rc5.60.g203738
