I'm seeing numerous crashes on x86 while running nashorn with the v8 benchmarks. This is on a dual-core machine, and the problem seems to go away when -XX:-BackgroundCompilation is added. Command line is:

/java/re/jdk/8/promoted/latest/binaries/linux-i586/bin/java -XX:+TieredCompilation -XX:+PrintCodeCache -jar /java/re/jdk/8/promoted/latest/binaries/linux-i586/jre/lib/ext/nashorn.jar run.js

Here are 5 of the crashes. hserr files are attached:
