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...
