[abc] FW: [abc-users] -O3 runtime error

Ok, guys, this is interesting because on my machine I am seeing exactly
the same problem. First I thought it was be related to our new lab
machines but reading this, maybe it is not. The strange thing is that
just a few weeks ago everything worked fine when I started to work with
the points-to analysis. Then all the sudden (?) I got paddle crash on my
machine using the Sun JVM. After consulting Ondrej I used JRockit, which
I just gave another try today and with JRockit it also seems to take
forever just as this user reports. Personally I have no clue what could
cause this.

Ondrej would you have a bit of time to look into this? If you need any
more information, please let me know.

Eric
