We have a multithreaded X86_64 application that we'd like to be able to run Google's gperftools CPU profiler. In the past we were blocked by problems with the X86_64 architecture. We have a renewed need for running the CPU profiler so I have just checked on the latest status of gperftools and libunwind, and I see that 1.1rc1 was released a few days ago. I have just done the following:
$ git clone git://git.sv.gnu.org/libunwind.git $ cd libunwind $ git checkout v1.1-rc1 $ autoreconf -i $ ./configure $ make $ make check There are two failures: FAILURE: expected 13, not 3 frames below signal frame FAIL: Gtest-dyn1 FAILURE: expected 13, not 3 frames below signal frame FAIL: Ltest-dyn1 This is an improvement, as we used to see 4 failures. My next step is to try gperftools and will report back results. In the meantime, should I expect to see the above two failures on X86_64? Is there any workaround for them?
