There's a big difference. A segfault is a machine error. The integrity
of the machine model has been violated, and the machine is in an
out-of-control state. In particular, the stack may be corrupted, so
stack unwinding may not be successful.
But, in an assert error, the machine is completely intact; the error is
at a higher level, which does not interfere with stack unwinding.
Damage is possible only if you've written your destructors/finally code
extremely poorly. Note that, unlike C++, it's OK to throw a new Error or
Exception from inside a destructor.
But with (say) a stack overflow, you don't necessarily know what code is
being executed. It could do anything.
Most segfault are null deference or unintizialized pointer deference.
Both are recoverable.
