Happens when we are in find_if_case_1, where we call:
delete_basic_block (then_bb);
The basic block we try to remove is this one:
;; basic block 5, loop depth 1, count 0
;; prev block 9, next block 6
;; pred:
;;

Done.
I have XFAILed the testcase instead of removing it again. I'll re-open the
missed optimization PR.

Please revert your patch. A missed-optimization problem is less severe than
this failure mode. Then, let's work out what's going on and what other options
are available.

Slightly more reduced testcase:
typedef enum yasm_module_type {
YASM_MODULE_ARCH = 0,
YASM_MODULE_DBGFMT,
YASM_MODULE_OBJFMT,
YASM_MODULE_LISTFMT,
YASM_MODULE_OPTIMIZER

So from 144r (peephole2) to 145r (ce3) it goes from:
;; Insn is not within a basic block
(code_label 48 47 49 11 "" [3 uses])
;; Insn is not within a basic block
(jump_insn 49 48 50 (addr_diff_vec:DI (label_ref:DI 48)

Ah, sorry, looked for the wrong number. The last pass which has the case_label
is:

Thanks for the explanation! I see the following two references in the
assembler file but I don't see any code_label references to those number in the
dumps.

There are a million reasons why labels can disappear in GCC. This happens
because GCC deletes or keeps labels based on ref counting (LABEL_NUSES and
friends) and this is just too fragile.
The way for you to narrow do
