    Description

      In every debug session (no matter which Qt example I try), the debugger halts with an error like:

      HEAP[spectrum.exe]: Invalid address specified to RtlValidateHeap( 00000000002D0000, 00000000047DDC40 )

      and with the stack trace pointing to some delete operation. This also happen on simple test examples using a clear() instruction which has an underlying delete operation. I posted one example of it on the forum, with its stack trace

      here

      This happens all the time, and makes debugging impossible unless I disable all the delete instructions e.g. using #ifdef QT_NO_DEBUG.
