------------------------------------
Summary: memcpy used on overlapping memory regions causes sanity
test failure
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
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.
