+
+We can use a dummy value here as we set up the buffer and stride
+further down in the constructor.

+Subject: [PATCH] Handle server name overflow properly
 
-Building from the 1.9.0 tarball using GCC 8.3.0 on Linux yields the following:
-
-tigervnc-1.9.0/vncviewer/vncviewer.cxx: In function ‘int main(int, char**)’:
-tigervnc-1.9.0/vncviewer/vncviewer.cxx:527:14: error: ‘char* strncpy(char*, const char*, size_t)’ specified bound 64 equals destination size [-Werror=stringop-truncation]
-       strncpy(defaultServerName, configServerName, VNCSERVERNAMELEN);
-       ~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-In function ‘void potentiallyLoadConfigurationFile(char*)’,
-    inlined from ‘int main(int, char**)’ at tigervnc-1.9.0/vncviewer/vncviewer.cxx:557:35:
-tigervnc-1.9.0/vncviewer/vncviewer.cxx:396:14: error: ‘char* strncpy(char*, const char*, size_t)’ specified bound 64 equals destination size [-Werror=stringop-truncation]
-       strncpy(vncServerName, newServerName, VNCSERVERNAMELEN);
-       ~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This commit ensures the buffer always has the null terminator.
+We need to make sure it is null terminated on truncation. We also
+need to avoid giving a too large size argument or modern gcc will
+complain.
