[jira] Commented: (HARMONY-3993) [drlvm][jit] Enumeration error
when running Dacapo lusearch
[ https://issues.apache.org/jira/browse/HARMONY-3993?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12501475 ]
Mikhail Fursov commented on HARMONY-3993:
-----------------------------------------
With a current build the crach is not reproducible in my environment.
I can reproduce it with r522129 with gc_gen only (a hour with gc_cc testing did not show any problems)
Applying patches I found that the problem is not reproduced after this commit:
"[r542523] HAEMONY-3941: [drlvm][gc_gen] EUT suite 'ui' crashes during stress
test execution when gc_gen is used with Out of Memory. This patch
gives a fix in two folds: to reserve more space in MOS when LOS
extension; to slide-compact LOS during los_alloc failure. This patch
also enhances the GC verifier to catch the corner case bug."
Xiao-Feng,
if the problem is not reproduced in your environment I suggest closing the issue.

> Project: Harmony
> Issue Type: Bug
> Components: DRLVM
> Environment: Win32, debug version
> Reporter: Qi Ji
>
> I found the vm reports assertion failure when doing enumeration recently.
> To reproduce the bug easily, you can check out revision 542129 to get the code that is easy to reproduce the bug. Change one line of code in gc_common.cpp (line:49) to permit a 16MB minimal heap size, which helps to reproduce the bug:
> - POINTER_SIZE_INT min_heap_size_bytes = 32 * MB;
> +POINTER_SIZE_INT min_heap_size_bytes = 16 * MB;
> and use the following command line:
> java.exe -Xms16m -Xmx16m -cp . -s large lusearch
