i have checked the sources of kprof -1.4.3 with a static code analysis tool (cppcheck).
It brought up an issue. The tool prints the following output:
[kprof/kprof/Log.cpp:222]: (all) Array index out of bounds
Take a look at the sourcecode:
snprintf(pos, sizeof(pos)-1, "%15s(%4d) ", file, line);
Indeed, the index of array-variable pos goes out of bounds
