There are a couple of SIGSEGVs and SIGBUSs, but most of the failures are an assertion:

EVALUATION It is caused by Sun Studio 11 C++ compiler bug 6629277 "destructor call for temporary object in switch statement missing in some cases in Studio11". Bad code is generated for DepChange::ContextStream::next() in dependencies.cpp. A simple workaround is to enclose the offending switch statement clause in curly brackets.
