About one year ago I met a very similar problem with the sun compiler.  
After a long debugging session I was able to track it to a specific  
compiler bug: loop counter was not incremented at loop exit (for  
sufficiently complicated loops). Reducing optimization to 1 for compiling  
iotk solved the problem.
