Confirmed, I'll have a look (another hit of this sanity check ...). We have
<bb 5> [local count: 1073312329]:
with two successors (one "dead" abnormal edge to .ABNORMAL_DISPATCHER) left
around by some pass not properly cleaning up.

--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
So it's CCP which turns
<bb 2> :
__cancel_routine_8 = func;
...
<bb 5> :
__cancel_routine.0_1 = __cancel_routine_8;
__cancel_routine.0_1 (0B);
into
<bb 5> :
func (0B);
but fails to invoke abnormal cleanup here. It's a general issue with the
propagation engine.

tree-optimization/107803 - abnormal cleanup from the SSA propagator
The SSA propagator is missing abnormal cleanup which shows in a
sanity check in the uninit engine (and missed CFG verification).
The following adds that.
PR tree-optimization/107803
* tree-ssa-propagate.cc (substitute_and_fold_dom_walker): Add
need_ab_cleanup member.
(substitute_and_fold_dom_walker::before_dom_children): When
a stmt can no longer transfer control flow abnormally set
need_ab_cleanup.
(substitute_and_fold_engine::substitute_and_fold): Cleanup
abnormal control flow.
* g++.dg/pr107803.C: New testcase.
