[ https://issues.apache.org/jira/browse/HARMONY-5434?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ilya Berezhniuk updated HARMONY-5434:
-------------------------------------
Environment: Linux/x86_64 release (was: Linux/x86_64)
> [drlvm][jit] Crash in reliability.api.kernel.thread.ThreadSuspendResume.ThreadSuspendResume
> -------------------------------------------------------------------------------------------
>
> Key: HARMONY-5434
> URL: https://issues.apache.org/jira/browse/HARMONY-5434
> Project: Harmony
> Issue Type: Bug
> Components: DRLVM
> Environment: Linux/x86_64 release
> Reporter: Ilya Berezhniuk
>
> I've got an intermittent crash in ThreadSuspendResume test on 16-core Linux/x86_64 machine.
> It occurs every ~5-10 run for me.
> I've checked on 4-core machine - the same crash occured on 35th run.
> Crash occurs for me in address 0x00002aaabd473da0; it belongs to memory area "2aaaae568000-2aaabd56b000 ---p", i.e. without read/write/execution rights.
> Investigation shows that this address is called from the code:
> ----------------
> 0x2aaabe473cb5: test %al,(%rax)
> 0x2aaabe473cb7: add %al,(%rax)
> 0x2aaabe473cb9: add %al,(%rax)
> 0x2aaabe473cbb: nop
> 0x2aaabe473cbc: callq 0x2aaabe473da0 <=================
> 0x2aaabe473cc1: add $0x8,%rsp
> 0x2aaabe473cc8: mov %eax,%r12d
> ----------------
> This code belongs to java.util.Random.nextDouble method.
> So the crash is probably because of race condition in compilation - or probably in something else...
