Description
I've found a memory leak in QXmlSchema.
It's easily reproductible using Qt's Xml Schema Validation Example.
$ valgrind --tool=memcheck --leak-check=full ./schema ==22308== 2,464 (104 direct, 2,360 indirect) bytes in 1 blocks are definitely lost in loss record 8,589 of 8,709 ==22308== at 0x4C2C54F: operator new(unsigned long) (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==22308== by 0x6035A8A: ???
