Hello

i ve got the following error on a C servor.

signal SEGV (no mapping at the fault address)

when running in dbx

a where in dbx give me this

here is the function which have the problem

void _log (struct msg_info * msg, union msg_param param)
{
	struct msgin_log * pin;
	struct msgout_log * pout;
	char * c;
	char Buffer[2048];
	char fname[255];
	
	time_t ti;
  struct tm * tm = NULL;

	FILE * fp = NULL;

	trace ("_log begin");

	pin = (struct msgin_log *)msg->data_in;
	pout = (struct msgout_log *)msg->data_out;
	msg->len_out = sizeof (struct msgout_log);
	memset (pout, 0, sizeof (struct msgout_log));
	trace ("_fin allocation");

	// reconstitution du nom du fichier de log support_sofi.client.yyyy-mm-dd.log
	time (&ti);
	tm = localtime (&ti);
	trace ("_fin time");

	strncpy ( Buffer, pin->InMsg, 2048 );
	sprintf ( fname, "support_sofi.client.%04d-%02d-%02d.log", tm->tm_year + 1900, tm->tm_mon + 1, tm->tm_mday );

	trace ("_fin sprintf");
	trace(fname);
	fp = fopen (fname, "a");
	trace ("_fin fopen");
	if ( fp != NULL )
	{
		trace ("_start fprintf");
		trace(Buffer);
		fprintf ( fp,"%s", "test" );
  	//fwrite (Buffer , 1 , sizeof(Buffer) , fp );
		//fputs(Buffer,fp);
		trace ("_fin fprintf");
		if (fclose (fp)!=0){
			trace ("fclose failed");
		}else{
			trace("fclose success");
		} 
		trace ("_fin fclose");
	 
	}

	//strcpy ( pout->OutMsg, "" );
	trace ("_log end");
}

this code work on a server but not on an other one, i would like to see why it doesn't work on the second servor.
Note that the core dump is created after the second call to the _log function

any help would be appreciated

thanks in advanced
