I got one crash issue on OpenJDK7 windows build.
I captured the stack trace of such a crash, which happens intermittently on my 64bit Windows 2008 server. But unfortunately I have no simple test case to reproduce this problem.
RtlInterlockedFlushSList+0x2ea (0x779F2A7F [ntdll+0x32a7f])
RtlInterlockedFlushSList+0x572 (0x779F2D07 [ntdll+0x32d07])
RtlInterlockedFlushSList+0x45d (0x779F2BF2 [ntdll+0x32bf2])
HeapFree+0x14 (0x755A14D1 [kernel32+0x114d1])
free+0x1c (0x7284016A [msvcr100+0x1016a])
free_netaddr+0x11 (networkinterface.c:107, 0x725A12AC [net+0x12ac])
getAllInterfacesAndAddresses+0xb6 (networkinterface_winxp.c:199, 0x725AB4C8 [net+0xb4c8])
Java_java_net_NetworkInterface_getAll_XP+0x12 (networkinterface_winxp.c:693, 0x725AB7AB [net+0xb7ab])
From the code at src/windows/native/java/net/NetworkInterface_winXP.c:195, I believe it is the dangling pointers that caused this problem. The uninitialized pointer netaddrP is exceptionally freed if the call to Windows API "GetIpAddrTable()" fails.
