Package: g++-4.2
Version: 4.2.1-6
Severity: normal
g++ seems to ignore exception handlers in unpredictable ways. I've
attached a minimal program that illustrates what's been happening to me.
It aborts with an uncaught exception ("terminate called after throwing
an instance of 'exception'"). But if you comment out either the line
instantiating a class that crashes in its destructor, or the line that
explicitly throws an exception, the exception is caught as expected.
