Re: Wrong Perf Backtraces

[ahmadkhorrami <ahmadkhorrami@xxxxxxxx>]

But the addresses do not match. Do you confirm this as a bug in 
libdwarf,...?

So I will ignore addresses without a matching symbol. But they do not 
seem reliable!

Could you tell me the name of the library that generates the raw 
addresses, so that I can try to debug it?

Regards.

you need debuginfo to resolve symbols and inlines,
raw addresses should be coorect
