Assertion failure during RaiseIR

Hi,

I'm getting an assertion failure that I can't seem to track down. I wondered if you might be able to help me.

I've enabled break on assertions, and it's breaking somewhere in PhaseList.DoPhaseList that I'm running over a ModuleUnit. This is the message:

Here is the stack trace:

phxd.dll!Phx.Asserts.AssertFailed(string expressionString = "!newType->IsAggregateType && !operandType->IsAggregateType", string messageString = "", string fileNameString = "e:\\sdkjul2007wix\\src\\phx\\types\\type-resolve.cpp", uint line = 763)

phxd.dll!Phx.Phases.PhaseList.DoPhaseList(Phx.Unit unit = {Project.Management.TreeManager::GetBranch (State: HasOriginalLayout HasRaisedEH IsPostFrameGenerated IsPostRegisterAllocated NeedRecoverFrameInfo NeedRecoverSymbolicId Lir)})

phxd.dll!Phx.PEModuleUnit.ProcessGlobalSymbols(Phx.PE.UnitListPhaseList unitListPhaseList = {IR Unit Function Phases (no control) [PhaseList]})

phxd.dll!Phx.PE.UnitListPhaseList.Execute(Phx.Unit unit = {C:\tmp\Project.Client.dll})

phxd.dll!Phx.Phases.Phase.DoPhase(Phx.Unit unit = {C:\tmp\Project.Client.dll})

phxd.dll!Phx.Phases.PhaseList.DoPhaseList(Phx.Unit unit = {C:\tmp\Project.Client.dll})

I have tracked down some of the functions being analysed where this failure occurs, but I can't seem to see any reason for this to happen, and I'm not sure which lines in the IR are causing this failure

Any help would be appreciated.

Thanks

Andy
