[boost] boost::basic_wrap_stringstream SIGBBUS with SunPRO

I'm running into numerous examples of the regression test programs
hanging/crashing today due to what may be a problem with
basic_wrap_stringstream.  Here's an example:

/home/nbde52d/src/boost-regression/results/bin/boost/libs/assign/test/my_vector_example.test/sunpro-5_3/debug/my_vector_example
--log_level=all
Running 1 test case...
Entering test suite "List Test Suite"
Entering test case "check_list_inserter"
../libs/assign/test/my_vector_example.cpp(98): info: test vec.size()
== 10u passed.
Exception in "check_list_inserter": signal: memory access violation
/home/nbde52d/src/boost-regression/boost/boost/test/impl/unit_test_suite.ipp(179):
fatal error in "check_list_inserter": Testing aborted
Leaving test case "check_list_inserter"
Leaving test suite "List Test Suite"

*** errors detected in test suite "List Test Suite"; see standard
output for details

Here's a stack trace from dbx (same program):
