--- Comment #1 from Richard Smith <richard-gccbugzilla at metafoo dot co.uk> --- While we're here, this check for overflow in consume_count is nonsense, and any decent optimising compiler is going to optimise away the overflow check: https://github.com/gcc-mirror/gcc/blob/master/libiberty/cplus-dem.c#L525 Testcase: $ echo '_Z4294967297x' | c++filt x Oops. It looks like item 2 in comment#0 was fixed recently (https://github.com/gcc-mirror/gcc/commit/b2dcfe3da47412480529c8591ba0433cd495fbe3) but item 1 is still live.
