callgrind function names are not shown in child processes

Question

Hi,

I have process A wich forks process B. A and B - are different application. Both compiled with -g flag.

to run it with callgrind I use command: valgrind --tool=callgrind --trace-children=yes ./A [params]

callgrind.out.xxx for parent process (A) contains function names. for child process(B) - it doesn't contains. What could be wrong here?

Thanks

Answer 1

Have you tried with latest version of valgrind ?

The only current problem which seems obvious to me is:

...you will have to make sure that the output file format string (controlled by --callgrind-out-file) does contain %p (which is true by default). Otherwise, the outputs from the parent and child will overwrite each other or will be intermingled, which almost certainly is not what you want.
