This issue is related to axis2c-unofficial.

It was introduced in 5a45fe1784b5: 
https://code.google.com/p/axis2c-unofficial/source/detail?r=5a45fe1784b541b8cabb
255a1c49e5af7bd12495

To workaround roll-back to previous changeset, compile and install 
axis2c-unofficial by entering those commands:

hg up -rc1e885257106

make && make install

After that you shouldn't see crash.

Hi Dmitry, I tried to reproduce the crash but was unable to...

I've just looked at the last changeset, saw that you reverted the code that 
provoked the crash, but saw that you also made some other modifications in 
guththila_xml_parser.c I didn't had the time to analyse those modifications 
yet, does it still fix the issue of the modified buffer?

Yes it fixes. Source buffer wouldn't get modified. Now Guththila only start 
unescaping symbols when you get element value or attribute value in the copy of 
the buffer.

To reproduce the issue see my description on 
https://issues.apache.org/jira/browse/AXIS2C-1628 . There is a test service 
which uses axiom_build_node_from_buffer.

One bad thing I see in your code: you allocating buffer using C runtime 
(strdup()), but deallocating it using Axis2c runtime (AXIS2_FREE() not free()). 
Not sure if it can cause problems.

This issue is not reproducible under valgrind (but reproducible under gdb). 
That means the problem could be a race condition.

Hi Dmitry,

I couldn't reproduce the bug, not even with the tests attached to 
AXIS2C-1628... I compiled it with/without optimization and runned it alone, in 
gdb and valgrind and  the error did not ocurr in my pc :(
Either way, David can you confirm that the patch solved the issue for you? If 
it did I'll just commit the patch to trunk.
