EXTRA RELEVANT SYSTEM CONFIGURATION :

This should not really matter.

$ ecj -version
Eclipse Java Compiler 0.780_R33x, 3.3.1, Copyright IBM Corp 2000, 2007. All rights reserved

A DESCRIPTION OF THE PROBLEM :
When importing a new package in eclipse, eclipse automatically refreshes and builds the package. During this process, the hotspot vm usually seg faults.

THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: Did not try

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Did not try

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Start eclipse, like so:
eclipse -consolelog -debug -vm openjdk/build/linux-i586/bin/java

(specifying "-vm path/to/libjvm.so" does not cause segfault- only when /path/to/bin/java)

1. Check out http://svn.mugshot.org/dumbhippo/trunk/
2. Import into project "trunk"
3. Close eclipse
4. run eclipse like above
5. delete project "trunk"
6. re-import project "trunk"
7. Compile (this should be done automatically by eclipse)

Steps 3-6 seem irrelevant, but I can more often reproduce the segfault by following those steps

EXPECTED VERSUS ACTUAL BEHAVIOR :
No seg fault.
