Daniel Pinyol commented on XERCESC-1451:
----------------------------------------
Since API is not compatible, is there any migration tutorial? I only found that
http://xerces.apache.org/xerces-c/migrate-archive-3.html#Migrateto300 , and I'm
not sure how to migrate DomBuilder, DomWriter,...
Thanks.
> Valgrind reports mismatched new/delete[] usage
> ----------------------------------------------
>
> Key: XERCESC-1451
> URL: https://issues.apache.org/jira/browse/XERCESC-1451
> Project: Xerces-C++
> Issue Type: Bug
> Affects 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:
> ==21267== Mismatched free() / delete / delete []
> ==21267== at 0x1B903D5D: operator delete[](void*) (vg_replace_malloc.c:161)
