Bus Error Vmstate

I wish the C standard would include means of packing/unpacking larger integer types to/from a sequence of smaller integers/characters so as to let the compiler use whatever approach is best on Please keep this bug open and track all the exchange of the JVM team here and resolve it after the problem is resolved with the JVM team.

I mean Ruby is not Scheme, there is no tail call optimization and those kinds of things. Being vulnerable to bus errors is a sign of bad management. All other users should be unaffected by this change. jaroslawr commented Dec 27, 2014 I would like to recap what the situation is: The ActiveSupport::Callbacks implementation from Rails 4.1+ turns a sequence of N callbacks into an N-level deep stack

It has problems in getting thread states. How far above a waterfall should you be to safely cross? Following go to C:WindowsSystem32wbem and rename the repository folder to repositoryold. That's what is causing the bus error in this case.

Will I still get the error now? Just adding a lot of callbacks to a class does not trigger this, neither does a huge amount of has_many relations in a single model. java version "1.6.0" Java(TM) SE Runtime Environment (build pxi3260sr2-20080818_01(SR2)) IBM J9 VM (build 2.4, J2RE 1.6.0 IBM J9 2.4 Linux x86-32 jvmxi3260-20080816_22093 (JIT enabled, AOT enabled) J9VM - 20080816_022093_lHdSMr JIT - FreeBSD makes me happy (as a server), no maintenance and I al… Unix OS Linux/ Unix Bash Shell: Navigating the File Tree Video by: Dototot Learn how to navigate the file

You can trigger a BUS error/Alignment Trap if you do something silly like do pointer math and then typecast for access to a problem mode (i.e.

It wouldn't be stack overflow protection, just memory write protection (this is a security hole if your program can rewrite itself). –Mark Lakata Jun 21 at 17:11 add a comment| up Attempting to access a unit larger than a byte at an unaligned address can cause a bus error. hmmm... which requires analyzing the dump file C:\Windows\javacore.20140929.120641.5268.0002.txt to determine the cause.If you don't know how to do it, please contact Support and open a ticket.

Does that mean that OS X Mavericks is buggy? In modern use on most architectures these are much rarer than segmentation faults, which occur primarily due to memory access violations: problems in the logical address or permissions. Oooh yes!

They can perhaps fix the SIGBUS in the Ruby interpreter, but I doubt they can do anything to legitimize nesting so many calls. mbj commented Dec 25, 2014 BTW: I think the MRI bug @jaroslawr reported is closely related to the one that gets triggered by mutant and described in mbj/mutant#265. POSIX describes SIGBUS as: Access to an undefined portion of a memory object. You set up an uint8_t array, add one, two, or three to the array's pointer and then typecast to a short, int, or long and try to access the offending result.)
