Subject [jira] Commented: (HARMONY-3861) [drlvm] DRLVM jvmti test PopFrame1 intermittently failed on Linux x86
Date Tue, 15 May 2007 11:15:16 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-3861?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12495957

Gregory Shimansky commented on HARMONY-3861:

Running the test 1000 times in a loop with -Xem:jet (in fact it appears that -Xem:jet is equivalent
to running JVMTI tests in default mode since ti.emconf doesn't contain any differences from
jet.emconf) produced no crash. Command line that I used is the following:

./lnx_ia32_gcc_debug/deploy/jdk/jre/bin/java -Xem:jet -cp ./lnx_ia32_gcc_debug/semis/jvmti.tests/classes:./make/tmp/junit.jar
-agentpath:./lnx_ia32_gcc_debug/semis/jvmti.tests/native/PopFrame1/libPopFrame1.so junit.textui.TestRunner

I wonder if some difference in CC/CI environment causes the crash. Is it possible to enable
core dumps when running CC/CI (using "ulimit -c unlimited") and use core dump to at least
get stack traces in the threads when crash happened?
