While testing this patch series, we found error messages which look like this:
Out of bounds address found:
Addr: 10370 DSO: /usr/local/lib/libgcc_s.so.1 d Map: 7f1b0c953000-7f1b0c968000 Symbol: 102d0-102e9 g _Unwind_DeleteException Arch: x86_64 Kernel: 3.10.23+ Tools: 3.13.rc1.g374a4d
Not all samples will be on the annotation output.
Please report to linux-kernel@vger.kernel.org
I first suspected it to be caused by this patch series, but I'm able to reproduce without these patches as of this commit:
a51e87c perf tools: Remove unused simple_strtoul() function
gdb attributes 0x10370 to a different/known symbol.
(gdb) x /i 0x10370 0x10370 <get_cie_encoding+160>: cmp $0x4c,%dl
Is this known? Could this possibly be caused by stale histogram entries from unmapped/remapped shared libs?
