Issue1339

With jython trunk.
$ ant test
....
[exec] test_grp
     [exec] #
     [exec] # An unexpected error has been detected by Java Runtime
Environment:
     [exec] #
     [exec] #  SIGSEGV (0xb) at pc=0xb7f193a2, pid=23860, tid=3084172176

     [exec] # Problematic frame:

This happens consistently and occurs with beta3 as well.

It looks like a jna problem.
Probably similar: http://markmail.org/thread/ej2yanxjoaktmc66

This is probably not at all helpful at the moment.
I'll try to reproduce it on Ubuntu.

No crash for me.
Ubuntu 8.04 x64
Jython trunk r6300

I tried the following JVM's (all 64bit)
java-1.5.0-sun-1.5.0.16
java-6-sun-1.6.0.07
java-6-openjdk (6b11-2ubuntu2.11)

On my Ubuntu 8.04 (32 bit), i got:

huo@bisonws0135:~/stuff/jython/jython-2.5b4$ ./jython
./Lib/test/test_grp.py 
Inconsistency detected by ld.so: dl-open.c: 623: _dl_open: Assertion
`_dl_debug_initialize (0, args.nsid)->r_state == RT_CONSISTENT' failed!
huo@bisonws0135:~/stuff/jython/jython-2.5b4$

using java 1.6.0_07 from Sun

Now i did the following:

 - grab the 3.0.9 jna.jar from https://jna.dev.java.net
 - put together a snapshot full-build using this jna.jar
 - installed this snapshot on Ubuntu
 - ran test_grp.py

This was successful:

huo@bisonws0135:~/stuff/jython/jython-2.5b4-jna$ ./jython
./Lib/test/test_grp.py 
test_errors (__main__.GroupDatabaseTestCase) ... ok
test_values (__main__.GroupDatabaseTestCase) ... ok

----------------------------------------------------------------------
Ran 2 tests in 0.085s

OK
huo@bisonws0135:~/stuff/jython/jython-2.5b4-jna$ 


The snapshot build is here:
http://jython.extreme.st/sharedfiles/jython_installer-2.5b4-jna.jar

The question now is: 
Can we simply replace our jna.jar with the latest released one (3.0.9) ?

Oti: upgrading to the latest jna sounds reasonable to me provided the
regrtests run.

No crash for me with jna.jar 3.0.9

Just for reference, the jruby and jna bugs relating to this are:
http://jira.codehaus.org/browse/JRUBY-3084
https://jna.dev.java.net/issues/show_bug.cgi?id=93

You should be able to just update jna to 3.0.9, but an update to
jna-posix 1.0.1 probably isn't a bad idea.  I did change the library
jna-posix loads from "c" to "libc.so.6" on linux to aid in avoiding this
issue.

cburroughs, Kevin, Wayne - many thanks for testing and helping!

trunk now uses the updated versions of jna and jna-posix, as suggested 
in msg4647.

The snapshot build 
(http://jython.extreme.st/sharedfiles/jython_installer-2.5b4-jna.jar) is 
now up to date, too. It was built from r6315.

Closing as fixed.
