Basically, I'm calling it like so: void __cyg_profile_func_enter(void *this_fn, void *call_site) { Dl_info functionInfo; dladdr(this_fn, &functionInfo; Dl_info call_siteInfo; dladdr(call_site, &callsiteInfo); syslog(LOG_INFO, "%s got called from within %s", call_siteInfo.dli_sname, functionInfo.dli_sname); } The problem is that although the function name is always good, the call site info is often bad. I'll get output like "???^H?^C?^XG??^A???", without the quotes. This isn't very useful. Any ideas on what I'm seeing and what I need to do to correct this?
