Debug Assertion Failed - Qt 5 RC1 - extraTryFontsForFamily

Hi
Having a serious issue with qt 5 RC1. When my application starts up, I receive the following:
Debug Assertion Failed!

Program: C:\Development\Qt\qtbase\plugins\platforms\windowsd.dll
File: f:\dd\vctools\crt_bld\self_x86\crt\src\dbgheap.c
Line: 1424

Expression: _pFirstBlock == pHead

After executing the line:
if (!db.writingSystems(family).contains(QFontDatabase::Symbol)) {
in the extraTryFontsForFamily call in qwindowsfontdatabase.cpp.

Not sure as to why this is happening - seems to be having an issue cleaning up the heap. Anyone care to shed some light?
Qt 5 RC1 compiled with the following flags:
C:\Development\Qt>configure -platform win32-icc -developer-build -opensource -nomake tests -nomake examples -debug-and-release -no-c++11 -confirm-license -opengl desktop -no-sse2 -plugin-sql-mysql -I C:\MySQL\include -L C:\MySql\lib -plugin-sql-odbc

Using Visual Studio 2012 with the latest Windows 8 Kit/latest intel compiler (2013).

Just realised I should have posted this in a more relative forum. Whoops.
