--- Comment #2 from Karine EM <k.even-mendoza at imperial dot ac.uk> ---
I also got this error with a bit different trace/pass in GCC-13:
======
void **a;
void b() { void **c = a; }
a;
=====
and the trace:
fuzzer-file-879.c:2:19: internal compiler error: tree check: expected class
'type', have 'exceptional' (error_mark) in useless_type_conversion_p, at
gimple-expr.cc:87
