> --------------------------------------------------------------------
>
> Key: XERCESC-2049
> URL: https://issues.apache.org/jira/browse/XERCESC-2049
> Project: Xerces-C++
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 3.1.2
> Environment: Debian unstable (sid) and Debian stable (jessie) on amd64
> Reporter: Bill Blough
> Attachments: moveChars_overlap
>
>
> On Debian Jessie (libc6 2.19, libstdc++ 4.9.2) and newer, sanityTest.pl fails
> its tests of XMLString::collapseWS.
> Tracing with GDB shows that XMLString::moveChars is corrupting the string. I
> think this is likely due to memcpy being used on overlapping memory regions.
> Replacing the memcpy in moveChars with memmove fixes the issue on my
> systems.
