1503.0. "Bugcheck on Digital UNIX 3.2g but not on 4.0b (high order bits corrupt)" by BER::BALAMIR () Tue Mar 11 1997 12:00

Hi
I have problem concerning DEC Threads under Digital Unix 3.2C and 3.2G

This is a multi threaded OSI Application , it uses the pthread 

it runs under Digital UNiX 4.0 B perfectly (because it use the libphreads.so)

It genaretes the following Dump-file under Digital Unix 3.2C or Unix 3.2G.

Is that a known problem. I looked at guru:: found out that are some patches

related to libphreads.so for  Digital Unix 3.2C and   Digital Unix 3.2F . I copied

used with no success . 

Why doed it run under Dgital Unix 4.0B , not on Digital Unix 3.2C  or  Digital Unix 3.2

Thanks 

For help



%DECthreads bugcheck (version V3.12-311), terminating execution.

%     The DECthreads library has detected an inconsistency in its internal
%   state and cannot continue execution. The inconsistency may be due to a bug
%   within the DECthreads library, the application program, or in any library
%   active in the address space. Common causes are unchecked stack overflows,
%   writes through uninitialized pointers, and synchronization races that
%   result in use of invalid data by some thread.
%     Application and library developers are requested to please check for
%   such problems before reporting a DECthreads library problem.
%     The information in this file may aid application program, library, or
%   DECthreads developers in determining the state of the process at the time
%   of this bugcheck. When the problem is reported, this information should be
%   included, along with a detailed procedure for reproducing the problem, if
%   that is possible. The 'detailed procedure' most likely to be of use to

.0> high order bits corrupt at 0x6b2280

This indicates that a cell which DECthreads uses as an atomic flag or spinlock
(and therefore which should contain only the values zero or one) contains a
non-boolean value.  One way that this could occur is if the application
specifies an invalid object (such as a mutex) in a call to DECthreads.  Another
way that this could occur is if something in the process has corrupted the value
at the indicated address.

.0> Why doed it run under Dgital Unix 4.0B , not on Digital Unix 3.2C  or  
.0> Digital Unix 3.2

There are two reasons.  The most important is that the V4 implementation is very
different from the V3 implementation, and the cell probably "moved" out from
under the corruptor (or the corruptor moved or disappeared) so that the
corruption is now nonexistent or benign.  The other reason is that this check
that you've hit is part of the DECthreads internal debugging code, and it was
never intended to be included in a production version of the library; some of
the V3 libraries inadvertantly contained it, but we removed it from the
production version of the library in V4 (for performance reasons).  (At least,
we intended to... :-)

Hi

If it is in the application , how can i find where it happpens

Thanks

Ahmet

.2> how can i find where it happpens

There is no good way.  You can do a "trace" on the location which is getting
corrupted, and hopefully you'll catch it.  However, doing the trace will slow
your execution down (depending on how fine a granularity you use), and it may
change a race condition so that the corruption never happens.

The best way is to review the code (by hand) in the application.  (But, this can
be a problem too, if there's lots of code.)
