memory leak in axis2c 1.5
Hello,
We found that there is about 2k memory leak in axis2c web service client
after each web service call . We traced down and found that the following
statement to free memory has been commented out in *
guththila_xml_reader_wrapper_xml_free* function of *
axiom\src\parser\guththila\guththila_xml_reader_wrapper.c*:
* if (data) AXIS2_FREE(env->allocator, data);*
When we uncomment out this statement, memory leak is decreased from 2k to
76 bytes. Due to time constraint, we didn't further trace down where is the
cause for the rest of memory leak. (see report [1]).
If you have special reason to do that, could you please let us know how to
fix the memory leak. If not, could you please patch this into axis2c source
tree?
best wishes
yong

Hi Yong,
Can you please create a jira in [1]. Then it is a lot easier to manage and
track
