Small test program still fail with gcc4.2.4

Core dump occurs if rethrow the exception from inner function. 
This occurs on AIX5.1 with gcc4.2.4, the test program is attached.
Compile it with: 
g++ -o exctest2 -static-libgcc -Wl,-bstatic -lsupc++ -lstdc++ exctest2.cpp
-Wl,-bdynamic

And run ./exctest2, the exception should be caught, but it always core dump at 
exc_catch_begin or exc_catch_end. 

The strange thing is, if I put std::cout.flush() before each 'throw;', the
issue disappear.
