Well, the compiler crashing with an unhandled exception is obviously  
always a compiler bug, rather than an indication that backward  
compatibility has been purposefully broken. The interleaved output of  
the unhandled exception and the errors is also strange.

Please file a bug report with complete code that can be fed to the  
compiler to reproduce the crash.
