xcb io crash

[nrathaus]

Hi,

I followed the instructions provided but when I run ./bin/bt_fuzzer I get:

[xcb] Extra reply data still left in queue
[xcb] This is most likely caused by a broken X extension library
[xcb] Aborting, sorry about that.
bt_fuzzer: ../../src/xcb_io.c:673: _XReply: Assertion `!xcb_xlib_extra_reply_data_left' failed.
Aborted

Any idea what could be the root cause?

Hi @nrathaus what OS are you using?
Is it Ubuntu 18.04?

[nrathaus]

I was using Ubuntu 20.04 LTS, is there a way you can "future proof" it so that Ubuntu 20.04 or 22.04 (even better) will be supported?

@nrathaus try sudo bin/bt_fuzzer --no-gui
Note that without sudo it won't work
