Comment 6 for bug 1905159

I'm currently trying to address these kind of warnings from gcc 8:

../../../src/libCom/error/errSymLib.c:165:17: warning: ‘strncpy’ output truncated copying between 1 and 5 bytes from a string of length 15 [-Wstringop-truncation]
                 strncpy ( pBuf,"<err copy fail>", bufLength );
                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
