[Linphone-developers] linphone Logging throws Access violation

[kmtegtmeier]

Hi, everyone!

Just tried to enable linphone logging, but it throws an Access violation 
at runtime.

FILE * logfile;

[......]

int main(int argc, char *argv[]){
    LinphoneProxyConfig* proxy_cfg;
    LinphoneCoreCbs* cbs;
    LinphoneAddress *from;
    LinphoneAuthInfo *info;
    LinphoneFactory *fac;

     logfile = fopen("C:\\Daten\\linphone.log", "w");
     if (!logfile) {
         printf("Cannot open logfile for writing logs because [%s]", 
strerror(errno));
     }

    const char* server_addr;
    signal(SIGINT, stop);

    running = true;

    printf("Setting up linphone core.\n");

    if (running) {

        fac = linphone_factory_get();
        cbs = linphone_factory_create_core_cbs(fac);

        linphone_core_set_log_file(logfile);
        linphone_core_set_log_level(OrtpLogLevel::ORTP_DEBUG);

        linphone_core_cbs_set_registration_state_changed(cbs, 
regstate_changed);
        linphone_core_cbs_set_call_state_changed(cbs, callstate_changed);

        lc = linphone_factory_create_core(fac, cbs,NULL,NULL);

        linphone_core_cbs_unref(cbs);

linphone_factory_create_core(fac,cbs,NULL,NULL) fails with Access 
violation at 0x00000014 (ntdll.dll)
Platform is Windows 10 x64, Visual Studio 2017, libs are from 
JUL-21-2017. If I set FILE to NULL (i.E. stdout),
everything works fine.

Has anyone experienced similar problems?
