Output(When executed on Visual studio 2008):
caught other exception (non-compliant compiler?)But, I was expecting the output to be:
unexpected called
caught int

Yes, as per the Standard the output should be[#1]:
gcc gives accurate result.
Note that, MSVC is notoriously buggy w.r.t handling exception specifications. Exception specifications are considered a failed experiment.
AFAIK, MSVC does not implement exception specifications, except for the empty ones (
