This first happened with a gcc function, _cpp_lex_token, that has the
usual jumps:
│1159e6c: ↓ jne 115aa32 <_cpp_lex_token@@Base+0xf92>
I.e. jumps to a label inside that function (_cpp_lex_token), and those
works, but also this kind:
│1159e8b: ↓ jne c469be <cpp_named_operator2name@@Base+0xa72>
I.e. jumps to another function, outside _cpp_lex_token, which are not
being correctly handled generating as a side effect references to
ab->offset[] entries that are set to NULL, so to make this code more
robust, check that here.
A proper fix for will be put in place, looking at the function name
right after the '<' token and probably treating this like a 'call'
instruction.
For now just don't draw the arrow.
