Valgrind reports mismatched new/delete[] usage
----------------------------------------------
Key: XERCESC-1451
URL: http://issues.apache.org/jira/browse/XERCESC-1451
Project: Xerces-C++
Type: Bug
Versions: 2.5.0, 2.6.0
Environment: Red Hat 9 (Shrike 2.4.20-6smp), Dell Precision 530
Valgrind 2.4.0
g++ 3.2.2
Reporter: Glenn Miyake
Valgrind reports a mismatch new/delete[]
MemoryManagerImpl::allocate(unsigned) appears to allocate using just new(size).
This memory is then incorrectly freed using array delete (delete []) in
XMLString::release.
Simply changing the release method to call "delete" does not work since it
appears that release is also used to free memory allocated with new [].
Partial valgrind output follows:
