Subject [jira] [Updated] (AXIS2C-1629) some code maybe cause segment fault
Date Thu, 28 Mar 2013 19:29:17 GMT

Alex Mantaut updated AXIS2C-1629:
---------------------------------

    Attachment: axis2c_log_no_system_env.patch

Hi, you're right, it doesn't make any sense to use log when system_env doesn't exist, and
in case of error this could make impossible to determinate the cause of error. 
Attached patch takes care of that, it shows the correct output to stderr (I think is the only
valid thing to do because there is no log available)
By looking at the code it seems that it might be necessary to have a better mechanism for
showing errors while the log is not available... (Perhaps another funct/macro in axutil_log)
But for now this seems the easier way to fix the issue...
