Re: [jira] Resolved: (XERCESC-1362) memory leak in reading
XMLURL
Hi Jesse,
to get the fix you need to download version 1.19 of
util/NetAccessors/Socket/UnixHTTPURLInputStream.cpp
(http://cvs.apache.org/viewcvs.cgi/*checkout*/xml-xerces/c/src/xercesc/util/NetAccessors/Socket/UnixHTTPURLInputStream.cpp?rev=1.19).
The fix is only in the current HEAD tag of CVS, and Xerces 2.6 has the same
problem.
If you need to apply the patch to your copy of Xerces 2.5 you will have to
manually extract the 4-5 lines I added and place them in the corresponding
place of version 1.16 of the same file.
