I feel like this was addressed but I couldn't find any references. The program
below prints the following:
Initialize
Create
Finalize
Finalize
Why is Finalize called twice? I thought those were supposed to be called in
pairs with initialize?
If you look at the generated code, you see that there is an implicit
try/finally block
and the finally block does a finalize.
call fpc_pushexceptaddr
movq %rax,%rdi
call fpc_setjmp
movl %eax,-92(%rbp)
cmpl $0,%eax
jne .Lj10
leaq -96(%rbp),%rdi
call P$TEST$_$TMANAGEDOBJECT_$__$$_CREATE$$TMANAGEDOBJECT
movq $INIT_$P$TEST_$$_TMANAGEDOBJECT,%rsi
leaq -96(%rbp),%rdi
call fpc_finalize
.Lj10:
call fpc_popaddrstack
movq $INIT_$P$TEST_$$_TMANAGEDOBJECT,%rsi
leaq -96(%rbp),%rdi
call fpc_finalize
movl -92(%rbp),%eax
