[Xorp-users] xorp_rtrmgr - Assertion failure

[Pavlin Radoslavov]

This particular bug was probably fixed already in CVS. Either get
the lastest code from CVS, or apply the following simple change to
libxipc/xrl_router.cc :

 #define trace_xrl(p, x) 						      \
 do {									      \
-    if (xrl_trace.on()) XLOG_INFO(string((p) + (x).str()).c_str());	      \
+    if (xrl_trace.on()) XLOG_INFO("%s", string((p) + (x).str()).c_str());     \
 } while (0)
