[DynInst_API:] Dyninst Issue with C++11 chrono

[ååè <zongyao.zhang@xxxxxxxxxxxxxx>]

Hi Doctors & experts:

    I found an issue with Dyninst handling C++ 11 chrono library calls:

        If I use chrono system calls in my code, Dyninst cannot work, the error is "segment fault" when I run the application which is instrumented.

        If I remove chrono system calls and the header of chrono, the instrumented application runs ok.

       

    Here is the code and steps to reproduce this problem:

        1, Download the package to a Ubuntu system(14.04LTS)

        2, Open a terminal and set the environment for Dyninst:

            export DYNINST_ROOT=/xxx/xxx/dyninst (the path of installed dyninstï

            export export DYNINSTAPI_RT_LIB=/usr/local/lib/libdyninstAPI_RT.so

        3, go to the directory "build"

        4, execute commands:

                cmake ..

                make

        5, you can see two executables are generated: chrono and without_chrono; you can run these two executalbes without any issue.

        6, now start instrumention by Dyninst:

                ./binst without_chrono out_without_chrono         // "out_without_chrono" is generated.

                ./out_without_chrono     //no error occurs.

               

                ./binst chrono out_chrono    // "out_chrono" is generated.

                run ./out_chrono

                "Segment fault. core dumped".

If you have any idea or answer, please do let me know.

Thanks,

Zongyao
