Subject [jira] Created: (HARMONY-1364) Stack parameters for Exception Handling not initialized and asserts on access
Date Fri, 01 Sep 2006 00:11:22 GMT
Stack parameters for Exception Handling not initialized and asserts on access
-----------------------------------------------------------------------------

                 Key: HARMONY-1364
                 URL: http://issues.apache.org/jira/browse/HARMONY-1364
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
         Environment: Tested on NT, but same code problem on Linux
            Reporter: Rana Dasgupta
         Attachments: assertfix

Symptom: 
-------------- On msvc build the following test hits an assert(0) in nt_exception_filter.cpp:240

The stack parameters in the overflow exception handling code are uninitialized. This is a
regression, since the test worked before.

Test case:
---------------
public class Stack { 
    static int depth = 0; 

    public static void func() { 
        depth++; 
        func(); 
    } 

    public static void main(String[] args) { 
        try { 
            func(); 
        } catch (Throwable th) { 
            System.out.println("First SOE depth = " + depth); 
            System.out.println ("Caught = " + th); 
        } 
    } 
} 

Fix: attached
----

Testing:
-----------

Ran all smoke tests against "build test" target. There is one failure( unrelated  to the current
issue of stack overflow ) on my test machine, but that is both before and after code changes.
However, I am attaching failure log below.

INFO: TEST test_jthread_get_all_threads start
ERROR: Assertion '(thread_count)==(i)' failed at C:\Harmony\drlvm\vm\tests\unit\thread\test_ti_instrum.c:65
ERROR: Assertion '(thread_count)==(0)' failed at C:\Harmony\drlvm\vm\tests\unit\thread\test_ti_instrum.c:39
INFO: TEST test_jthread_get_all_threads: FAILED
