It fails because a shortage of memory is detected under the st_alloc_frames(depth) memory request within st_get_trace().
It happens due to enormous stack depth (about 457384257 frames for me).
So, the jit compiled code of Test.func() leads to SIGSEGV raising. However,
the stack overflow issue is not detected because the fault address doesn't take up a position
within defined thread's stack.
So, it should be investigated further why do the jited code or the way of its invocation furnish a fault address
plased out of the allocated stack?
And are the 457384257 frames acceptable for such cases if about 2097152 stack size is supposed for a thread?

[jira] Updated: (HARMONY-1786) Stack Overflow Error detection fails
on Linux
Posted by "Rana Dasgupta (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/HARMONY-1786?page=all ]
Rana Dasgupta updated HARMONY-1786:
-----------------------------------
Attachment: stackfixes
This patch fixes the issue reported. The issue is the same as the failure of the smoke test "StackTest". The virtual memory corresponding to the thread stack and alternate signal handling stack need to be mapped before usage. The patch also renables asserts that had been temporarily disabled in the code when we were aplying BBC. Duplicate initialization issues have also been fixed. The patch also reenables "StackTest".
All cunit and smoke tests pass. kernel tests demonstrate exactly the same behaviour before and after the patch.

[jira] Commented: (HARMONY-1786) Stack Overflow Error detection

Rana Dasgupta commented on HARMONY-1786:
----------------------------------------
I think the test case is a clone of the StackTest ( smoke test ). mprotect() fails with ENOMEM on the main thread when setting up the overflow guard. ENOMEM is a resource failure, sometimes raised when kernel structures cannot be allocated.
