jvm crash using eclipse

[Patrick Mackinlay]

The problem happens regardless of whether I compile the jdk with or
without ipv6 support, however I do have an IPv6 address as well as an
ipv4 one. I use subclipse-1.6.2, this is the only thing that I think
will use TCP/IP (does subclipse run the command line client or do the
connection itself?). The only other things that will use TCP/IP are the
unit tests, but eclipse will often crash before I have run any.

The error is intermittent it can happen 10 times in 5 minutes or once a
day. It seems to be more stable if I turn off "Build automatically"
(which will presumably reduces the amount of concurrency), it also seems
to crash most often when opening or closing projects. However, it is so
intermittent that my observations could well be luck related.

I have compiled my jdk with debug symbols and looking at the core dump
with gdb gives the following stack trace for the thread that bombs:

Looks like the signal happens in PhaseChaitin::gather_lrg_masks whatever
that is.

Also note that tomcat6 is stable, but I do not load tomcat very much at
all (only ever has one occasional HTTP client, so no request concurrency).

At the moment my jdk is compiled with ipv6 support, I am going to try
compiling it again with this option off. I will use a
portupgrade -fR eclipse
so that all upstream dependencies are also recompiled.
