While testing this patch series, we found error messages which look like

Out of bounds address found:

Addr: 10370
DSO: /usr/local/lib/ 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

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?
