Crash in libqt (sometimes) when performing GUI interactions #7973
Description
Version and Platform (required):
- Binary Ninja Version: 5.2.8722 (stable)
- Edition: Non-Commercial
- OS: Ubuntu Linux
- OS Version: 22.04
- CPU Architecture: x86_64
Bug Description:
Sometimes when interacting with UI elements binary ninja crashes. Such as searching for a type or going to an address with g. It is sporadic and I have not found a way to reproduce it.
Steps To Reproduce:
It is sporadic and I have not found a way to reproduce it. The steps for reproducing I have is:
- Open a binary and perform some UI actions such as searching in the types view or going to a function with
g. - Most of the time nothing happens. Sometimes binary ninja crashes.
Expected Behavior:
No crash should occur.
Screenshots/Video Recording:
None.
Binary:
This happens regardless of the binary opened with binary ninja.
Additional Information:
The crash is a NULL pointer dereference inside of libqt6.
I managed to catch the crash with gdb attached to binary ninja and got the stacktrace and a coredump. The entire coredump is 6gb so i couldn't upload it to the portal. I have attached the gdb session showing the backtrace, register content dump and disassembly of the crashing function in an attachment here.
