Markus,
I run Eclipse 3.4 (64-bit) on 64-bit Java and Ubuntu Hardy Heron (64-
bit). It was crashing pretty consistently for a while (more about
that here:
http://www.jroller.com/page/phidias/?anchor=hardy_heron_eclipse_woes
and here:
http://www.jroller.com/page/phidias/?anchor=hardy_heron_eclipse_update)
until I added this to the eclipse.ini file:
-XX:CompileCommand=exclude,org/eclipse/core/internal/dtree/
DataTreeNode,forwardDeltaWith
I had tried the MaxPermSize trick but that didn't solve this problem.
The main problem with most of these types of crashes is that eclipse
spits out a log file that includes references to native code where the
problem is occurring. The file's a little difficult to read, but
there's usually some indication in the file as to what the problem
is.
