IndexError: index out of range in Binary Ninja API code

[droe]

[Default] Traceback (most recent call last):
[Default]   File "/Applications/Binary Ninja.app/Contents/MacOS/plugins/../../Resources/python/binaryninja/plugin.py", line 361, in _high_level_il_instruction_is_valid
[Default]     return is_valid(view_obj, func_obj[instr])
[Default]   File "/Applications/Binary Ninja.app/Contents/MacOS/plugins/../../Resources/python/binaryninja/highlevelil.py", line 2477, in __getitem__
[Default]     raise IndexError("index out of range")
[Default] IndexError: index out of range

Repro:

• Open target
• Click on function call in HLIL
• Press Escape

Mere presence of a plugin with is_valid handler seems to be enough, it is not needed to execute a plugin command.

Workaround:

• Removing is_valid handler from plugin command registration.

Reported a bug upstream: Vector35/binaryninja-api#6254

Yeah I've been experiencing this, seems to be a recently introduced upstream bug

Disabled is_valid in 5b80ee5 to work round this issue.
