    Description

      Using QDomText::splitText causes memory to be leaked each time it's called.

      Valgrind-Massif shows the memory being allocated under QDomText::splitText, in QString::mid and QString::fromLatin1_helper, amongst other places.

      Building and running the attached will cause the memory used by the process to increase linearly over time as it runs.
