Segfault - removing a device from list

[Rob Mason]

Hi,

This is not a critical issue, but when clearing out some old backup dive
computers from my device list, I get a segfault straight after confirming
deletion. I'm using subsurface 4.7.8 on Mint Linux 18.3. Problem doesn't
appear on my Win10 laptop.

Thanks

hi,

i would have pointed you out towards our most recent development
version, but it seems that our tooling did not build an AppImage:
https://github.com/Subsurface-divelog/subsurface/releases/tag/continuous

looking at this: https://subsurface-divelog.org/download/
are you using the PPA build for Linux Mint or the AppImage one?

you could do the following to provide us with more details about the crash

see if GDB is present:
gdb -v

if not install it:
sudo apt-get update
sudo apt-get install gdb

navigate to the subsurface binary folder and do:
gdb ./subsurface

to start the debugging type:
r

< make it crash via the UI >

to obtain a backtrace call:
bt 30

share the output here.

thanks

Hi - I'm using the PPA (AppImage has never worked for me). The GDB output
is below. Hope this helps! Thanks for the response.

Hi - I'm using the PPA (AppImage has never worked for me). The GDB output
is below. Hope this helps! Thanks for the response.

thank you for the stack trace.
i will add this to our issue tracker at github.

this could be already resolved in the latest development version.
