JIT *) "compile.cpp":662
[ https://issues.apache.org/jira/browse/HARMONY-3728?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ilya Leviev updated HARMONY-3728:
---------------------------------
Attachment: HARMONY-3728_add_markup_update.patch
Patch updated as header file name have changed from port_nonatomic.h to port_threadunsafe.h
> [drlvm][jit] Race condition at function enum JIT_Result compile_do_compilation_jit(struct Method *,class JIT *) "compile.cpp":662

> Key: HARMONY-3728
> URL: https://issues.apache.org/jira/browse/HARMONY-3728
> Project: Harmony
> Issue Type: Bug
> Components: DRLVM
> Reporter: Ilya Leviev
> Priority: Minor

> TC reports about next race condition.
> As it not affect correctness of execution I have marked it by special API for prevention of further alarms on this race.
> DEPENDENS: The patch may be applied only after committing patch for JIRA HARMONY-3537 which contains API with markup functions.
> Here is stack traces of the issue.
> Write -> Write data-race
> Memory write at "compile.cpp":662 conflicts with a prior memory write at "compile.cpp":662
