llvm dev - Aug 2008 - [LLVMdev] Assertion Failure: Not all catch info was assigned to a landing pad

I'm getting a very stubborn assertion failure that I don't understand.
After I insert a call to an externally defined function into an invoked
function, llc spits out the following assertion failure when I compile the
bytecode:

llc: SelectionDAGISel.cpp:4912: virtual bool
llvm::SelectionDAGISel::runOnFunction(llvm::Function&): Assertion
`FuncInfo.CatchInfoFound.size() == FuncInfo.CatchInfoLost.size() &&
"Not all
catch info was assigned to a landing pad!"' failed.

I looked at the SelectionDAGISel.cpp code but I have no idea what the
problem is or how I can fix it.  I've tried setting different parameter
attributes to no avail.  Maybe somebody can explain this failure to me?

Many thanks,
Marc

Nevermind.  Problem solved.  Was putting the function call at the front of
some landing pad basic blocks and forking the control flow afterwards, which
confused llc.

Sorry for the trouble.
