Segmentation fault on Debian buster

[XReyRobert]

Hi All,
I've tried to compile lineapple on debian buster (inside a docker container - see attached Dockerfile)

Compilation goes through but I have a segmentation fault trying to execute...
Any idea where to start looking ?

(Interestingly I compiled it and ran with success in a docker container but using a arm32 version of debian stretch)

Build with debug option (see Makefile) and run it in gdb; when it seg faults do a bt to get the traceback.

Also, as a workaround if you just want to run the emulator, you can re-enable the old, slow, singlethreaded video update behavior by adding this to your linapple.conf:

Singlethreaded = 1

However, if you could send me that backtrace from gdb, it would help fix this issue.

[ghedger]

Added fallback to singlethreaded if error creating worker thread. I'm not very familiar with Docker; I suspect what may have happened is it's a singlethreaded machine. Installing Debian Buster now (VirtualBox, amd64) to check behavior there.

In the absence of additional info that's the best we can do at the moment...

Attempt #1 to install this Debian failed (something about mirrors and proxies; changing mirror location didn't seem to help); Trying attempt #2

[ghedger]

Attempt #2 to install this Debian failed with a different error ("Error installing base system"). Trying attempt #3, this time not using graphical installer.

[ghedger]

Attempt #3 failed, same error. Going to delete the entire VM and start over with Attempt #4

[ghedger]

Attempt #4 failed. Attempt #5 failed as well, but got really far along in the process like Attempt #1. I've spent enough of my time trying to recreate the reported environment; Suggest someone with a working instance of Debian 10.3 attempt to reproduce (and ideally fix) the issue. Thank you.

Thanks @ghedger, I'm still investigating butI think a bad DISPLAY parameter or non accessible X11 server is the reason...

[ghedger]

Also, the video_draw_mutex application to CreateDIBSections (thank you) may indeed have addressed this.

My sincere apologies for not being successful in reproducing this environment. VirtualBox has not been kind lately...
