[drlvm][jit] JET crashes in deep recursion if started with JVMTI agent
----------------------------------------------------------------------

                 Key: HARMONY-3721
                 URL: https://issues.apache.org/jira/browse/HARMONY-3721
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
         Environment: Linux/x86, harmony-hdk-r531333
            Reporter: Ivan Popov


All JDWP tests of jdktools JPDA module failed on Linux/x86 after the recent changes in JET code for SSE2 support (r530955). Tests work fine on Windows/x86 and in -Xint mode on Linux/x86.

When application is stared with JVMTI agent, JET falls into deep recursion and crashes in random place probably due to stack overflow. This happened after Agent_OnLoad() has been executed but before VMInit callback is invoked. Typical stack trace is the following:

STDERR> SIGSEGV in VM code.

To reproduce this bug run any JDWP test, for example org.apache.harmony.jpda.tests.jdwp.VirtualMachine.VersionTest:

1. create Harmony JDK with federated build:
    svn checkout https://svn.apache.org/repos/asf/harmony/enhanced/trunk
    cd trunk
    ant

2. goto jdktools directory, add junit to classpath, and launch test case:
    cd working_jdktools
    export CLASSPATH=<...>/trunk/common_resources/depends/jars/junit_3.8.2/junit.jar
    ant test -Dbuild.module=jpda -Dtest.case=org.apache.harmony.jpda.tests.jdwp.VirtualMachine.VersionTest

3. see results in <...>/trunk/working_jdktools/build/test_report/html/index.html

It is possible also to run test directly from command line:
   cd working_jdktools
   deploy/jdk/bin/java -classpath ../common_resources/depends/jars/junit_3.8.2/junit.jar:build/tests/classes \
   org.apache.harmony.jpda.tests.jdwp.VirtualMachine.VersionTest
