Thanks for your support I did it in other way ..... :) Yes I'm upset because no one has tried or looked the test program i had sent (I sent that program because there some genius guys, who only talk about the code like Linux kernel guys, can easily figured out the issue :( and mistake i had did :(. I'm little unlucky).
Everyone asking me to verify the lib with working* "foo"* test program :( , If that program works fine does it mean the lib is working fine? :(. I'm sorry I could not able write a better mail. I am very poor in sentence framing :( will improve it ... thanks for bearing my English and thanks for your help. :) :) I will not bother you guys again .. :) Thanks Sasi On Thu, Feb 23, 2012 at 12:45 PM, Arun Sharma <[email protected]> wrote: > On Wed, Feb 22, 2012 at 10:56 PM, Sasikanth <[email protected]> > wrote: > > Arun, > > > > I clearly told stack trace not working because of invalid frame pointer > > ...without a proper frame pointer unwind not able to unwind the stack and > > asked her does this libunwind supports similar to GDB. > > I'm having a hard time parsing this sentence - but if your question > is: can libunwind unwind the stack properly in the absence of frame > pointers using DWARF CFI information, the answer is yes. > > Since this is working for you with GDB, I'm guessing that the DWARF > CFI info is there and GDB is able to find it, but libunwind is not.
