In one fatal error code path, snprintf() is given its output buffer asan input string.
src/jdk.jdwp.agent/share/native/libjdwp/debugInit.c line 645: (void)snprintf(buf, sizeof(buf), "JDWP %s", buf); Proposed fix is of course: (void)snprintf(buf, sizeof(buf), "JDWP %s", msg); This was found by compiling with GCC 8.1 Bug: https://bugs.openjdk.java.net/browse/JDK-8214061 webrev: http://cr.openjdk.java.net/~sgehwolf/webrevs/stooke/JDK-8214061/01/webrev/ Thanks, -Simon Tooke
