chop trace -begin 100 -end 300 ./hello_world
Error occurs：chopstix driver: error: Tracer:: track_mmap: Child did not stop
I find the status_ get 0 after waitpid, and the correct stopped signal should be 5 (status_ = 1407).

Can you provide the necessary information to reproduce the issue? At least:

  • platform (power, s390, riscv, x86)
  • source code of the hello_world binary and the compilation command.

with that, then I can get started.

The Child did not stop error is the result of not providing the right set of begin addresses. If child did not step, it is because the -begin address of 100 is never executed. You might need to use other set of addresses. Please check the updated documentation on how to do so. To trace the function my_func you can use:

chop-marks ./hello_world my_func

to get the begin/end addresses to use. Closing the issue.
