Hi !
I wanted to locate a delay in a Linux kernel module and to do this added a few
addr1=__builtin_return_address(0);
addr2=__builtin_return_address(1);
addr3=__builtin_return_address(2);
...
to the code if a cirtain delay was reached - the problem was that it
segfaults if I try to grab __builtin_return_address(2) which I don't
understand why , or maby more precisely, how can I check how deep I
can backtrace calls ?
thx !
