with seg fault on the recursive call of a synchronized method
[ https://issues.apache.org/jira/browse/HARMONY-3010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12469754 ]
Alexey Varlamov commented on HARMONY-3010:
------------------------------------------
Reproduced on truly x86 SUSE10 SMP box, MyStack2 outputs on release build:
SIGSEGV in VM code.
Stack trace:
and hangs.
On Xeon SUSE9 32bit SMP box, it segfaults too but does not hangs and does not provide backtrace.

> The attached test crashes with the following message on Linux SUSE9 ia32:
> SIGSEGV in VM code.
> Stack trace:
> 1: locktable_get_fat_monitor (/nfs/ins/proj/drl/coreapi/esemukhi/svn/drlvm/trunk/vm/thread/src/thread_native_thin_monitor.c:655)
> 2: hythread_thin_monitor_try_enter (/nfs/ins/proj/drl/coreapi/esemukhi/svn/drlvm/trunk/vm/thread/src/thread_native_thin_monitor.c:310)
> 3: IP is 0x416A05BD <native code>
> 4: ?? (??:-1)
> <end of stack trace>
> Segmentation fault
> If to remove the "synchronized" modifier from the "test()" method declaration, the test passes.
> On SUSE9 Linux em64t the crash does not depend on the "synchronized" modifier: it just crashes with the wording:
> Segmentation fault
> (see HARMONY-2972)
> The attached test is the slightly modified smoke test stress.Stack.
