PCSX2 hang on exit (Linux)...
#1
Version : 1.3.1-20151205020727 (git)
------------------------------------------------

First I will give some details on how I compiled the latest version:

I compile using Fedora 23 (32bit) on a virtual machine.

Use the following compile options:

./build.sh --clean --release --gtk3 -DSDL2_API=FALSE

I run the application on Fedora 23 (64bit).

Everything works fine and I can load games as normal. The problem comes when I come to close the program. The window appears to hang on exit. If I look at the terminal output I get the following:


Code:
Decommitting host memory for virtual systems...
Releasing host memory maps for virtual systems...


It gets no further and I have to force close the application.

The last time I built PCSX2 was about 2 months ago and I had no troubles then.

Replace release by dev. Retry and attach gdb into the process. Dump all backtrace with this command "thread apply all bt"

I tried the following command:

gdb PCSX2 (followed by run)

The application runs and when I try to exit I get the following:

So I ran the dnf debuginfo-install ............... line and it installed about 1.8 gigs worth of debug info but for some reason, the next time I run GDB it still gives me the same response asking me to install the debug info?

I know it is definately installed because if i try to run the dnf command again it says it is already installed?

Is it because I am trying to debug a 32bit binary on a 64bit version of GDB?

Unfortunately I have to go out now and wont be able to try anything until tomorrow. If you could leave some instructions I will get back to you as soon as I can.

Thanks.

you need a PCSX2 devbuild to get debug symbol.

And just run the above gdb command (my first post)

Ok so I have had no luck getting GDB to show anything. I have attached the output so you can see that the build type is set to devel

I run the following command "gdb PCSX2"
followed by "run"
I then close the PCSX2 application
I run the following command (still within GDB) "thread apply all bt"
Nothing happens apart from the GDB prompt re-appearing again
I try running "bt"
I get the following response "No Stack"

I dont know if it is the effect of gdb but it almost appears that the hang does not happen when launching via gdb. If I launch without gdb, when i close the program the main window closes but the "PCSX2 Program Log" window remains open and it appears to hang (I have left it for a long time to prove that it never closes).

Launching via gdb does not cause the "PCSX2 Program Log" window to remain.....

Maybe the reason there is no call stack is because the program doesn't crash?

On the plus side, I have discovered that I dont need the virtual machine to build it anymore as the 32bit dependencies no longer conflict with the 64bit versions like they did on older versions of Fedora so now I can build on my 64bit machine Smile

Do the contrary start/shutdown PCSX2. Attach gdb on the hanging windows. Something like that (check google)
gdb ./bin/PCSX2 `pidof PCSX2`

That did the job. I learned something new there.

Hopefully this gives some idea of what is going on:

Do a "info thread" maybe it will give the name of the thread. However it could an nvidia driver bug

Sorry, I just realized that was my release version and not my Dev one.

Hmm. Might be the console redirection stuff.
