/*
 * FULL PRODUCT VERSION : java version "1.4.0-rc" Java(TM) 2 Runtime
 * Environment, Standard Edition (build 1.4.0-rc-b91) Java HotSpot(TM) Client
 * VM (build 1.4.0-rc-b91, mixed mode)
 *
 *
 * FULL OPERATING SYSTEM VERSION :
 *
 * glibc-2.2.4-19.3 Linux 2.4.9-6smp #1 SMP i686 Red Hat Linux release 7.2
 * (Enigma)
 *
 * ADDITIONAL OPERATING SYSTEMS :
 *
 *
 * EXTRA RELEVANT SYSTEM CONFIGURATION : 2 CPUs
 *
 * A DESCRIPTION OF THE PROBLEM : When starting Java with "java
 * -Xrunhprof:cpu=times ..." the program will execute normally, but the JVM
 * crashes before the CPU statistics are written to the file.
 *
 * The effect is identical to that of bug 4489387, but in JDK 1.4 RC1, this bug
 * will only occur in a rarer setting. See the attached log and the bug
 * reproducing source code for details.
 *
 *
 * STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : 1. Compile the attached sources.
 * 2. java -Xrunhprof:cpu=times CrashTest 3. Fiddle with the loop counts
 * until the bug manifests reliably.
 *
 * EXPECTED VERSUS ACTUAL BEHAVIOR : I expected the CPU profiling data to be
 * written to a file. Actually, the JVM crashes. In rarer cases, it hangs.
