Subject [jira] Commented: (HARMONY-4215) [drlvm][reliability] assert in JIT while unwinding stack (during enumeration)
Date Thu, 02 Aug 2007 09:41:53 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-4215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12517190
] 

Gregory Shimansky commented on HARMONY-4215:
--------------------------------------------

I the few last days when I ran this test in the loop I have seen only the following types
of failures. All the times there is a crash on an assertion check in GC (note obj pointer
is bad):

>	gc_gen.dll!get_obj_info_raw(Partial_Reveal_Object * obj=0xdeadbeef)  Line 164 + 0x23
C++

 	gc_gen.dll!collector_forward_object(Collector * collector=0x016d2ca0, Partial_Reveal_Object
* p_obj=0xdeadbeef)  Line 35 + 0x9	C++

 	gc_gen.dll!forward_object(Collector * collector=0x016d2ca0, Partial_Reveal_Object * * p_ref=0x0501f6f8)
 Line 96 + 0xd	C++

 	gc_gen.dll!nongen_forward_pool(Collector * collector=0x016d2ca0)  Line 222 + 0x9	C++

 	gc_gen.dll!collector_thread_func(void * arg=0x016d2ca0)  Line 186 + 0x9	C++

 	hythr.dll!thread_start_proc(void * arg=0x00382f38)  Line 710 + 0x9	C

 	hythr.dll!_threadstartex(void * ptd=0x004267b8)  Line 241 + 0xd	C

 	kernel32.dll!77e66063() 	


This happens about once in 100 runs on win32 for me. I haven't seen any other types of crashes
mentioned in this bug report.
