[jira] Created: (HARMONY-1661) [DRLVM][GC] gc_alloc() next to high
bit of size is not reset on allocating finalizible objects
[DRLVM][GC] gc_alloc() next to high bit of size is not reset on allocating finalizible objects
----------------------------------------------------------------------------------------------
Key: HARMONY-1661
URL: http://issues.apache.org/jira/browse/HARMONY-1661
Project: Harmony
Issue Type: Bug
Components: DRLVM
Environment: All
Reporter: Ivan Volosyuk
gc_alloc() allocation path for finalizible object incorrect again.
Fix for HARMONY-1588 added the flow. 'in_size' may have next to high bit set for object size. This indicates that the object has special features (is finalizible) and cannot be processed by fast path.
Changing in_size to size in slow path fixes the problem.
Bug is reproducible by java.lang.Runtime kernel test in interpreter mode. After the fix test passes for me.
