Question

I could not find the information where are exception class instances created during exception handling ? In which memory area (stack, heap, static storage, etc.) ? I assume it is not on the stack because of stack-unwinding …

Answer 1

From the standard:

15.2.4: The memory for the temporary copy of the exception being thrown is
allocated in an unspecified way,
except as noted in 3.7.3.1.

And 3.7.3.1 says:

3.7.3.1: All objects which neither have dynamic
storage duration nor are local have
static storage duration. The storage
for these objects shall last for the
duration of the program (3.6.2,
3.6.3).
