You should definitely recompile every user library; the ABI
changed. Though recompiling the kernel isn't necessary.
The old libraries also did not have the __rethrow symbol, which
is the symptom you're seeing. All C++ code that is not compiled
with -fno-exceptions will, with the newer compiler, include code
to clean up after any exceptions that can be thrown through
them. This includes calls to a library function called
__rethrow and stubs calling terminate (). This is not something
visible in user code, though. If know what you look for, you'll
know it happens for stack-local objects with destructors (I
might be forgetting the proper names of things).
