IndexError: No function has been found for the chunk

[RobinDavid]

Hi here,

I am encountering an issue trying to obtain a function from a chunk. The function get_function_by_chunk raises an IndexError issue. A PoC to reproduce the error is the following:

from quokka import Program

p = Program("libquic.dylib.quokka", "libquic.dylib")

f = p.fun_names['_quic_frame_parse_DATAGRAM']

p.get_function_by_chunk(f.calls[-1])

The faulty binary is the following: libquic.dylib.zip

Tested on:

• IDA 8.2
• Quokka: 0.5.7
